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

open62541 open62541
open62541 1.5.0 before 1.5.7 has an integer overflow in UA_DataType_fromStructureDescription() that wraps the 16-bit memSize field for large custom structure definitions, so a malicious OPC UA server can make a client overflow the heap when it loads remote DataTypes, crashing it or enabling code execution. Fixed in 1.5.7. CVSS 3.1 8.1.
Grav Grav
Grav 2.0.15 through 2.2.12 still lets page editors smuggle a data directive past the callable allowlist, using unset-name@ or an integer field key, to invoke arbitrary public static methods such as Folder::delete. The vendor says the 2.2.2 fix was incomplete and 2.2.13 fixes this route. CVSS 3.1 8.8.
Aider-AI Aider
Aider through 0.86.2 auto-loads a repo .aider.conf.yml with no trust prompt, and its notifications-command and editor values are later run through a shell, so opening an attacker repo in Aider can run commands as the user. CVSS 4.0 8.5.

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.

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.
