AI Security Agent Achieves RCE on GitLab Default Configuration via Dependency Chain
andreamichi · x · 2026-07-25
Security researchers successfully achieved Remote Code Execution (RCE) on GitLab in its default configuration, aided by a security AI agent built by @depthfirstlabs.
Unlike most historical vulnerabilities that reside in the web or application layers, this exploit targeted the low-level gem dependency chain. By sending crafted JSON data, they triggered deeply buried memory-corruption vulnerabilities, allowing them to take full control of the GitLab application server.
