Plain English Summary

AI-powered analysis for quick understanding

An attacker can exploit a flaw in the Cursor code editor to gain control of the system by manipulating Git settings, allowing them to run harmful commands without any user interaction. This vulnerability affects versions prior to 2.5 and can lead to remote code execution when certain Git hooks are triggered.

Technical Description

Cursor is a code editor built for programming with AI. Sandbox escape via writing .git configuration was possible in versions prior to 2.5. A malicious agent (ie prompt injection) could write to improperly protected .git settings, including git hooks, which may cause out-of-sandbox RCE next time they are triggered. No user interaction was required as Git executes these commands automatically. Fixed in version 2.5.
