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.
Legcord Legcord
Legcord 1.1.0 through 1.3.0 fails to validate theme IDs in its theme IPC handlers, letting script in the Discord page escape the themes directory to launch executables, delete directories, and write files.
Legcord Legcord
Legcord 1.1.0 through 1.3.0 lets script in the Discord page write any config key, so an attacker can persistently add Chromium proxy flags and route all client traffic through an interception proxy.
WWBN AVideo
AVideo's safeString() strips tags before decoding entities and runs twice, so doubly-encoded entities in video titles survive sanitization and execute as stored XSS on trending, gallery, embed, and playlist pages.
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.
