CVE-2025-64110
Cursor is a code editor built for programming with AI. In versions 1.7.23 and below, a logic bug allows a malicious agent to read sensitive files that should be protected via cursorignore.

This could allow a malicious agent to read protected files. This issue is fixed in version 2.0.
