CVE-2026-63093 Anysphere, Inc. CVE debrief
CVE-2026-63093 is a remote code execution vulnerability in Cursor for Windows version 3.2.16. The vulnerability allows remote attackers to execute arbitrary code 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. This vulnerability has a high CVSS score of 8.7 and is considered a high-severity issue. Developers and users should take necessary precautions to avoid exploitation.
