Issue no. 42 · The security zine
Security is all about context.
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.
vm2 vm2
A prefix-match flaw in vm2's NodeVM external-module resolver lets untrusted guest code load non-allowlisted modules through the host require, escaping the sandbox.
Project-MONAI MONAI
MONAI's bundle engine resolves _target_ values to arbitrary importables and passes $ expressions to eval(), so a malicious bundle runs code on load.
Project-MONAI MONAI
A local user with write access to a shared MONAI cache directory can plant a malicious pickle that executes code in another user's pipeline.
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.
