Intelligence Summary
Security researchers describe DuneSlide vulnerabilities affecting the Cursor AI IDE. Crafted inputs can perform zero-click prompt injection to escape Cursor’s sandbox. Once sandbox boundaries are crossed, attackers may run arbitrary code on the underlying operating system. The issue increases risk for developers using Cursor to process untrusted content or repositories. Users should update Cursor if patches are available and reduce exposure to untrusted prompts until mitigations are applied.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
