- Description
- Cursor for Windows version 3.2.16 contains a binary planting vulnerability that allows remote attackers to achieve arbitrary code execution by placing a malicious git.exe file in the repository root directory. When a developer clones and opens a crafted repository, Cursor automatically resolves and executes the workspace-resident git.exe during IDE startup and on a recurring timed cadence without any user interaction, running the malicious binary under the privileges of the current user.
