We successfully achieved an RCE on GitLab in its default configuration. Historically, most GitLab RCEs have lived in the web or application-logic layers. This time, guided by the @depthfirstlabs spirit, we went deeper: into the low-level gem dependency chain beneath GitLab. The result? By sending crafted JSON data, we could exploit memory-corruption vulnerabilities buried deep in that chain and take control of the GitLab application server. @depthfirstlabs brings together some of the smartest people, and is building the best security AI agent. Follow our work, and come join us! Read more about this in the comment...

We've been tracking public CVEs where AI-generated code introduced the vulnerability. vibe-radar-ten.vercel.app 50k+ advisories scanned. Dozens of confirmed cases so far. Claude Code, Copilot, Cursor, and others all show up. Common bug classes include XSS, command injection, SSRF, and path traversal. And these are just the cases that leave metadata traces. The real number is almost certainly higher. Open source, from Georgia Tech SSLab: github.com/HQ1995/vibe-secur…

“Earlier this year at the DARPA AIxCC event, Team Atlanta discovered a null-pointer dereference in SQLite, which inspired us to use it for our testing to see if we could find a more serious vulnerability.”

Excited to see Project Zero's blog on their LLM-powered zero-day discovery! Glad that our Team Atlanta work is helping inspire new approaches in vulnerability research. We'll share more LLM-based bug finding techniques at AIxCC too! 🔍

Welcome to my talk!!
Replying to @zhaiyizhuo
@zhaiyizhuo will be presenting her work @USENIXSecurity today on automatically recognizing sanity checks (i.e., type checks), which are then used to prune redundant sanitizer checks and reduce runtime performance overhead from sanitizers. #usesec24 @laosong @rakingleaves
