Practical security thinking for systems that increasingly write, deploy, and operate themselves. Fewer buzzwords. Better evidence. Occasional memes.

Known exploitation already skipped the prioritization meeting.
ImageMagick ImageMagick
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a stack-based buffer overflow in the handling of bzip2-compressed images, so a crafted image can overwrite stack memory during decoding and crash the process or corrupt memory. CVSS 3.1 8.1.
Parse Server Parse Server
Parse Server contains an authentication bypass for apps whose custom auth adapter subclasses the exported AuthAdapter class: the subclass validation methods are never called and an inherited default accepts any authData, so attackers can sign up, link identities, or log in as existing users for that provider. CVSS 4.0 9.1.
vLLM vLLM
vLLM from 0.9.2 before 0.24.0, when running with P2pNcclConnector, copies the X-Request-Id header into the request ID and extracts a decode address from it with no allow-list, so an API caller can force a prefill worker to connect to an attacker host and send it the NCCL unique_id and KV-cache tensors. CVSS 3.1 8.2.
Live demo · try it right here
Find leaked secrets without leaking them.
Paste code, config, or logs below. 112 detectors run entirely in your browser and return redacted findings, reasoned risk scores, and rotation guidance. Nothing uploads. Nothing phones home.
Inspect source material
No upload step exists. Files are read by your browser, scanned in memory, and discarded when the tab closes.
Findings
Ready when you are.
Add source material on the left. Results are pattern matches, not proof that a credential is active.
Latest transmissions
For the work after the scanner finishes yelling.
A field guide to agentic vulnerability management (with an actual off switch)
A practical operating model for introducing agents without confusing automation, authority, and accountability.
Finding vulnerabilities is getting cheaper. The backlog has noticed.
AI compresses the cost of discovery, but the expensive parts of vulnerability management still begin after the finding exists.
The vulnerability ticket is an interface, not a filing cabinet
A useful vulnerability record should help an owner decide and act—not merely preserve scanner output.
