Security researchers have disclosed a high-severity vulnerability affecting the Cursor IDE, allowing arbitrary code execution on a developer’s machine through a seemingly routine repository interaction. According to findings by AI pentesting platform Novee Security, once a developer cloned and interacted with a malicious repository, the IDE’s AI agent could trigger embedded Git logic, resulting in attacker-controlled code execution. “The root cause is not a flaw in Cursor’s core product logic, but rather a consequence of a feature interaction in Git, one that becomes exploitable the moment an AI agent starts autonomously executing Git operations inside a repository it doesn’t control,” said ...
