Unpatched Cursor Vulnerability Exposes Users to Code Execution
An unpatched vulnerability in Cursor on Windows can be triggered for code execution when a developer opens a repository in the application, Mindgard reports.
Cursor is one of the most popular AI-assisted development environments, with more than 7 million active users.
The security defect, Mindgard says, is straightforward: when opening a repository, Cursor would automatically execute a malicious git.exe binary in the project’s root without warning the user or asking for approval.
“The vulnerability is not theoretical and does not depend on a complex chain of exploitation, prompt injection, model manipulation, jailbreaks, memory corruption, or sophisticated attacker tradecraft. Exploitation simply requires a developer to open a project containing a git.exe binary in the repository at the root,” Mindgard says.
According to Mindgard, the issue exists because, when loading a project, Cursor looks for Git binaries in multiple locations, including the workspace itself.
