Traefik SNI check is skipped when TLS state is nil on Go 1.27 builds, bypassing client certificate routers

Traefik before 2.11.58 and 3.7.14 skips its SNI check when request TLS state is nil, which happens for HTTP/2 requests with the http scheme pseudo-header on Go 1.27 builds, so unauthenticated clients can reach routers requiring client certificates without presenting one. Official builds use Go 1.26 and are not exposed, per the Traefik advisory. CVSS 3.1 8.7.

CVE-2026-114637Disclosed

Traefik experimental FastProxy pool can hand an NTLM-authenticated backend connection to an unauthenticated client

Traefik from 3.2.0 before 3.7.14, when experimental FastProxy is enabled, pools plain HTTP backend connections without pinning NTLM or Negotiate authenticated connections to their frontend connection, so an unauthenticated client can be served as a victim on a reused backend connection. CVSS 3.1 8.7.

CVE-2026-114640Disclosed

Traefik Ingress NGINX HTTP router forwards forged Ssl-Client identity headers to backends

Traefik from 3.7.0 before 3.7.14 forwards client-supplied Ssl-Client headers on the plaintext HTTP router for Ingresses using auth-tls-pass-certificate-to-upstream, so when ssl-redirect is disabled an unauthenticated attacker can impersonate any mutual TLS identity a backend trusts from those headers. CVSS 3.1 8.7.

CVE-2026-114642Disclosed

Traefik NTLM round tripper reuse applies one service TLS policy to another service backend

Traefik from 2.11.0 before 2.11.58 and from 3.0.0 before 3.7.14 stores its NTLM and Kerberos backend round tripper in a connection slot not keyed by ServersTransport, so an unauthenticated client can arm it on one service and have another service backend connection made with the first service TLS settings, bypassing its root CAs, server name and certificate verification. CVSS 3.1 8.7.

CVE-2026-115372Disclosed

Incus restricted projects can still inject mkfs arguments through block.create_options on volume update, copy and move

Incus 7.3.0 before 7.5.0 rejects block.create_options only on direct volume creation, so a restricted project user can set it through volume update, copy or move and have it appended to the mkfs command line run as root when a pool formats the new volume. CVSS 3.1 8.5, CVSS 4.0 9.0.

CVE-2026-115376Disclosed

Incus custom volume copy skips the source access check when the source type is omitted

Incus 7.0.1 before 7.0.2 and 7.2.0 before 7.5.0 treats a custom volume create with a source volume but no source type as a copy, without the source access check that applies to explicit copies, so a project-restricted client can copy and read any other project volumes, snapshots and configuration. CVSS 4.0 8.3.

CVE-2026-115377Disclosed

Incus migration streams can plant symlinks that write host files as root

Incus before 6.0.7, 6.1.0 before 7.0.2 and 7.1.0 before 7.5.0 replays instance and volume migration streams with rsync or btrfs receive, which follow symlinks planted in the stream, so a malicious migration source can write attacker-controlled files to arbitrary host paths as root. CVSS 3.1 9.9.

CVE-2026-115384Disclosed

Wasmtime async callback results are not validated, overflowing the native stack and escaping the sandbox

Wasmtime 39.0.0 before 48.0.4 and 49.0.0 before 49.0.2 does not validate the result types of component-model-async callback functions, so a malicious guest can write about 16 KB of chosen data to the native stack, overwrite return addresses, crash the host or escape the sandbox. CVSS 3.1 9.9.

CVE-2026-76298Disclosed

Splunk Enterprise PostgreSQL sidecar password can be derived from the cluster ID in search job logs

Splunk Enterprise below 10.4.4 and 10.2.8 derives the PostgreSQL sidecar superuser password from the search head cluster identifier that appears in search job logs, so a user without admin or power roles can derive it and run arbitrary operating system commands as the Splunk user on search head cluster members.

CVE-2026-100236Disclosed

DPDK GSO header handling can read and write out of bounds on guest packets

A flaw in the DPDK GSO library: when software GSO copies packet headers into a new mbuf it does not check that the header fits in the source first segment or the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation, so a remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write. Red Hat rates it CVSS 3.1 8.6.

F5 rates it CVSS 4.0 8.7 (CVSS 3.1 7.5), affecting the 5.6.0 line before 5.7.0.

CVE-2026-15176Disclosed

Heap overflow in NGINX alias and rewrite handling can crash workers or run code

A vulnerability exists in NGINX Plus and NGINX Open Source when a location uses the alias directive together with rewrite and a set or return directive referencing the request_filename variable, or when that variable is used in an access log format: crafted HTTP requests can cause a heap buffer overflow in the worker process, restarting it, and can execute code where ASLR is disabled or bypassed. F5 rates it CVSS 3.1 8.1 (CVSS 4.0 9.2).

CVE-2026-91184Disclosed

AuthenticationFilter realm injection in NGINX Gateway Fabric can expose co-tenant secrets

NGINX Gateway Fabric renders the realm fields of a namespaced AuthenticationFilter verbatim into the shared data-plane nginx.conf, so a namespaced authenticated attacker can craft a realm value that injects arbitrary NGINX directives into that Gateway's data-plane config, potentially reading co-located tenants' mounted secrets, SSRF via proxy_pass, the pod ServiceAccount token, or hijacking other tenants' routes. F5 rates it CVSS 3.1 8.8, affecting 2.4.0 before 2.8.0.

CVE-2026-100606Disclosed

Flowise SSO invitation flaw lets anyone claim a pending invite

Flowise through 3.1.4 (enterprise/platform mode with SSO) has an authentication bypass in the SSO login path: when an SSO callback arrives with an email matching a user in INVITED status, the server copies the stored single-use invitation tempToken into the registration check instead of requiring the caller-supplied token. Anyone who can authenticate at a configured SSO provider with a pending invitee's email can take over the invitation and its organization access. No patched version is available.

CVE-2026-100607Disclosed

Flowise matches SSO users by email alone, enabling full account takeover

Flowise through 3.1.4 resolves SSO and local-password users solely by email, without storing provider or subject-identifier bindings. An attacker can authenticate as any existing user by claiming their email at any configured SSO provider, gaining complete access to chatflows, credentials, and API keys. No patched version is available.

CVE-2026-100608Disclosed

Flowise BullMQ dashboard lets any tenant user see and touch every queue

Flowise through 3.1.4 does not enforce authorization on the BullMQ admin dashboard. In queue mode with the dashboard enabled outside cloud mode, the /admin/queues mount validates the JWT but performs no role, permission, or workspace scoping, so any authenticated user, including the lowest-privileged member of any tenant, can view queues and job payloads across the instance (chat inputs, credentials in overrideConfig, chatflow definitions) and use write actions like retry, remove, and promote. No patched version is available.

CVE-2026-100631Disclosed

Parse Server lets anyone delete every device registration with no credentials

Parse Server before 8.6.90 (and 9.0.0 before 9.10.1-alpha.9) does not validate the type of client-supplied installation fields before building database queries in the device-token deduplication logic. An unauthenticated remote attacker who knows only the public application ID can inject query operators to make the elevated deduplication cleanup delete every device registration in the application, killing push delivery until every client re-registers. No workaround other than upgrading exists.

CVE-2026-100656Disclosed

Netty HttpServerCodec can be drowned by a single pipelined connection

Netty's HttpServerCodec tracks the HTTP method of each still-unanswered pipelined request in an unbounded queue. A remote, unauthenticated attacker who pipelines HTTP/1.1 requests on one connection while withholding reads can grow that queue without bound, exhausting heap and denying service. Fixed in 4.1.138.Final and 4.2.18.Final.

CVE-2026-100657Disclosed

Netty STOMP decoder leaks one buffer per connection until memory runs out

Netty's StompSubframeDecoder allocates a chunk buffer while waiting for a frame's terminating NUL byte and never releases it if the byte never arrives. A remote peer can leak one allocator buffer per connection by sending a well-formed frame body and withholding the NUL terminator, accumulating memory for the process lifetime. Fixed in 4.1.138.Final and 4.2.18.Final.

CVE-2026-100660Disclosed

Netty HTTP/3 QPACK encoder keeps peer-controlled state forever

Netty's HTTP/3 codec retains unbounded per-stream QPACK encoder state keyed by the peer-controlled QUIC stream ID, released only when the remote decoder sends a Section Acknowledgment or Stream Cancellation. A remote, unauthenticated HTTP/3 client that advertises a non-zero dynamic-table capacity and omits the mandatory acknowledgments can grow heap without bound over a single connection. Fixed in 4.2.18.Final.

CVE-2026-100661Disclosed

Netty HTTP/3 QPACK decoder can be stalled into a quadratic memory blowup

Netty's HTTP/3 QPACK prefixed-integer decoder does not bound the number of continuation bytes it processes. A remote, unauthenticated peer can send an endless run of continuation bytes on a QPACK unidirectional stream; each decode re-scans the whole accumulated buffer, yielding quadratic CPU cost and unbounded heap growth. Fixed in 4.2.18.Final.

CVE-2026-100662Disclosed

Netty HTTP/3 QPACK encoder stream trusts a 2 GiB length declaration

Netty's HTTP/3 QPACK encoder-stream instruction decoder accepts an attacker-declared string-literal length of up to roughly 2 GiB with no per-instruction cap. A remote, unauthenticated peer that declares a huge literal length and trickles fewer bytes than declared makes the per-connection buffer grow without bound, ending in OutOfMemoryError. Fixed in 4.2.18.Final.

CVE-2026-100663Disclosed

Netty mistranslates CONNECT request-targets, letting proxies tunnel the wrong authority

Netty's HTTP/3 codec mishandles HTTP/1 CONNECT authority-form request-targets when converting to HTTP/3: the CONNECT target's host is emitted as the scheme, the path becomes /, and the HTTP/1 Host header becomes the authority, or the target is dropped entirely. In an HTTP/1-to-HTTP/3 proxy, a client can bypass tunnel allow-lists and egress policy with a CONNECT whose Host header names a different authority than the request-target. Fixed in 4.2.18.Final.

CVE-2026-100664Disclosed

Netty HTTP/3 gateway trusts the Host header over the absolute request-target

Netty's HTTP/3 codec builds the :authority pseudo-header from the HTTP/1 Host header before considering the authority of an absolute-form request-target, contrary to the HTTP/1.1 rule that the request-target authority must win. A remote client can send 'GET https://trusted.example/admin' with 'Host: attacker.example' so authorization and routing decisions split from what the upstream HTTP/3 peer receives. Fixed in 4.2.18.Final.

CVE-2026-100665Disclosed

Netty QUIC skips hostname verification with plain trust managers

Netty 4.2.11.Final through 4.2.17.Final contains an incomplete hostname-verification fix in the QUIC certificate verification path when using a plain X509TrustManager: the BoringSSL verify callback discards the SSLEngine, so endpoint identification never runs even when HTTPS verification is configured. A network-path attacker can present a certificate for the wrong hostname that the trust manager accepts. Fixed in 4.2.18.Final.

CVE-2026-100669Disclosed

Grav web.config case trick exposes secrets on IIS

Grav before 2.0.25 ships web server configuration samples whose access-control deny rules are matched case-sensitively. In web.config for IIS, every deny rule sets ignoreCase='false', overriding the IIS default; on case-insensitive NTFS, an unauthenticated remote attacker can vary the case of a folder or extension (e.g. requesting /user/CONFIG/system.YAML) so no deny rule matches and the static file handler returns the file, disclosing configuration secrets or account password hashes. Fixed in 2.0.25; operators must re-copy the corrected sample files after upgrading because the installer heal does not touch web.config or lighttpd.conf.

CVE-2026-100670Disclosed

Grav blueprint guard bypass turns a user admin into super-admin

Grav CMS 2.0.14 through 2.0.24 has a privilege escalation in the group and account blueprints: the access map guard 'admin.super' is resolved by the field's exact path, so a submitted flat dot-notation key like 'access.admin.super' matches no blueprint rule, survives filtering, and is written by setNestedProperty, which splits on dots and rebuilds the nested value. An authenticated backend operator with admin.users but not admin.super can grant admin.super to their own account or group, escalating to full super-admin with control over configuration, plugins, themes, the file manager, and all accounts. Fixed in 2.0.25.

CVE-2026-100671Disclosed

Grav page cache serves a stolen admin session cookie to visitors

Grav 2.0.19 through 2.0.24 (and 1.7.x with content Twig explicitly enabled) renders page content from a page-write user through a Twig sandbox that allowlists get_cookie(), returning any cookie of the current request, including the session cookie, server-side where HttpOnly offers no protection. The finished output is stored in a page-content cache keyed without any session or user dimension. A page published by a page-write user can capture the session identifier of the next administrator who views it, and the cache then serves that identifier to unauthenticated visitors, who replay the cookie to authenticate as the administrator. Fixed in 2.0.25; 1.7.x is outside the backport scope.

CVE-2026-100672Disclosed

Grav Comments plugin leaks emails and server paths with no login

The Comments plugin for Grav CMS through 1.2.10 registers an admin handler that returns comment data as JSON without any authentication check: it branches on isAdmin(), which only indicates the admin service is registered on the route rather than that the visitor is authenticated, and it echoes the JSON before the classic Admin plugin would render its login screen. On a site using the classic Admin plugin with Comments enabled, an unauthenticated remote attacker can request the comments admin route and retrieve every comment from the last 7 days, including commenter email addresses and the absolute server filesystem path of the data file. Fixed in 1.2.11, which requires an authenticated user with admin.comments or admin.super and removes the absolute filePath.

CVE-2026-100673Disclosed

Grav Data Manager stored XSS hands attackers the admin's session

The Grav Data Manager plugin 1.0.1 through 1.4.4 renders stored data entries in the item-detail view without escaping, applying Twig's raw filter, in some cases after a striptags call that PHP's strip_tags bypasses by preserving allowed tags with attributes. An unauthenticated visitor who submits a front-end form whose submissions are saved to user/data can store an HTML payload that executes as JavaScript in the session and origin of an administrator who later opens that entry in the classic admin panel, running with the administrator's privileges and CSRF token. Fixed in 1.4.5.

CVE-2026-100682Disclosed

Budibase ZIP upload writes attacker files as root through symlinks

Budibase Server before 3.45.0 extracts user-supplied ZIP archives in the PWA icon upload endpoint without proper symlink validation. A BUILDER-role attacker can craft a malicious ZIP with leaf symlink entries followed by duplicate file entries to write arbitrary files as root, enabling remote code execution. Fixed in 3.45.0.

CVE-2026-100683Disclosed

Budibase column rename turns a column name into SQL injection

Budibase before 3.45.0 builds MySQL and MSSQL column-rename DDL by interpolating identifiers directly into a raw query string without applying its identifier-quoting helpers. An attacker with DDL rights on a connected datasource can create a column whose name contains a backtick or quote plus SQL; when a builder later renames that column through the UI, the embedded quote terminates the identifier and the injected SQL runs as the Budibase datasource user (MySQL connections allow stacked statements), enabling arbitrary reads, writes, or destructive operations outside Budibase's permission model. Fixed in 3.45.0.

CVE-2026-100684Disclosed

Budibase SSO invite claim hands attackers admin on a plate

Budibase 3.41.0 before 3.45.0 has an authentication bypass in the OIDC/SSO login path: when no existing user matches the incoming SSO subject, the server looks up pending invites by the IdP-asserted email alone, without validating an invite code or requiring email_verified. An attacker who can register at a trusted IdP and assert a victim's invited email claims the pending invite with all its privileges, including builder and admin.global, for full tenant compromise. Fixed in 3.45.0.

CVE-2026-100685Disclosed

Budibase chat-links endpoint spills cross-workspace identity data

Budibase before 3.45.0 fails to scope the GET /api/chat-links endpoint by workspace. A builder with access to a single workspace can enumerate chat identity link records across all workspaces in the tenant, retrieving user IDs and external chat service identifiers from workspaces they have no permission to access. Fixed in 3.45.0.

Hugo Node.js sandbox misses symlinks, exposing build-machine files

Hugo v0.161.0 through v0.165.0 runs Node.js tools (PostCSS, TailwindCSS, Babel) under the Node.js permission model to restrict file reads to the project directory, but the model validates only the lexical path and follows symlinks pointing outside the allowed set. A contributor can commit a symlink such as assets/css/x.css pointing at a sensitive file plus a PostCSS plugin that reads it, disclosing any file the Hugo build process can read, potentially embedded in the published site. Fixed in v0.166.0, which fails the build when a symlink resolves outside the allowed paths.

Hugo symlinked theme mount roots leak files into builds and published sites

Hugo after v0.123.0 and before v0.166.0 stopped symlink confinement checks at the mount root itself, so a theme or vendored module could contain a symlink at a mount root (for example themes/mytheme/assets pointing outside the module). Files behind the symlink were readable during builds via resources.Get and could be published to public/ via static mounts, bypassing the rule that theme and module mount sources must be local paths. Fixed in v0.166.0.

Adminer pre-auth SSRF turns the login page into an internal network oracle

Adminer 6.0.0 through 6.0.1, with the official ClickHouse driver plugin loaded, is vulnerable to pre-authentication server-side request forgery. An unauthenticated attacker can submit auth[driver]=clickhouse with auth[server] set to an arbitrary URL, making the Adminer server POST 'SELECT version()' to that host; when the target returns a non-2xx status, the raw response body lands on the login page. That enables internal network and port reconnaissance and leaks sensitive details from internal error pages. Fixed in 6.0.2.

nodemailer address parser can be wedged into a quadratic backtracking stall

nodemailer before 10.0.6 has a denial-of-service vulnerability in the addressparser free-text fallback regex, which exhibits quadratic backtracking. Crafted email header values with long whitespace-free runs can block the Node.js event loop for tens of seconds, taking the service down. Fixed in 10.0.6.

Red Hat Certificate System ACL tie-break lets agents author CA issuance profiles

A tie-breaking bug in the pki-core v2 REST ACL filter resolves colliding literal and wildcard ACL keys by lexicographic comparison instead of specificity, letting the Certificate Manager Agents group's lower-privileged profiles.approve override the Administrator-only profiles.create required by POST /v2/profiles/raw.
