CVE-2025-61593Network attack vector

Code execution via case-insensitive file overwrite

Published Oct 3, 2025 · Updated Oct 3, 2025

Code injection in Cursor CLI Agent 1.7 and earlier allows attackers to execute code by overwriting protected configuration files. Its sensitive-file check compares paths case-sensitively, so alternate-case paths resolve to protected .cursor/cli.json files on case-insensitive filesystems. Exploitation requires prompt injection and user interaction in a context the agent processes; successful writes can execute code with the user's privileges.
