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

ModelTC LightLLM
LightLLM through 1.2.0 exposes an unauthenticated RPyC server with pickle deserialization in the router profiler service when started with --enable_profiling, letting attackers execute arbitrary code by sending crafted serialized objects.
ModelTC LightLLM
LightLLM through 1.2.0 multimodal deployments expose an unauthenticated RPyC cache service with pickle deserialization on all interfaces, letting attackers send crafted serialized objects to execute arbitrary code.
ModelTC LightLLM
LightLLM through 1.2.0 lets unauthenticated attackers exhaust KV-transfer worker memory through the NCCL control channel's exposed_set_value method when started with --pd_trans_mode nccl, crashing workers and triggering node failure.
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.
