What the vulnerability does

01Description

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. An attacker who has already achieved prompt injection, or a malicious model, could create a new cursorignore file which can invalidate the configuration of pre-existing ones. This could allow a malicious agent to read protected files. This issue is fixed in version 2.0.
