Provenance

Reported as

When Cursor opens a repository, it automatically runs git.exe from the project's directory without validation, allowing a planted malicious git.exe to execute.

Mechanism

When Cursor opens a repository, it automatically runs git.exe from the project's directory without validation, allowing a planted malicious git.exe to execute. This defeats the application's own security model by executing untrusted binaries without user consent.

Detection & mitigation

Monitor for unexpected git.exe processes spawned from non-standard paths, especially from user-writable directories. Implement application control policies to block execution of binaries from untrusted locations.
