CVE-2026-48124
Cursor is a code editor built for programming with AI.
Overview
CVE-2026-48124 is a known-severity vulnerability. It was published on June 15, 2026.
Technical description
Cursor is a code editor built for programming with AI. In versions prior to 3.0.0, the Cursor Desktop could execute workspace-defined Claude hook commands from .claude/settings.local.json without dedicated user approval. A malicious workspace or agent-created file could configure hooks that run local commands in the user's context when an agent turn ends. This could allow sandbox escape, persistence across turns, local data access, or follow-on compromise. This issue has been fixed in version 3.0.0.
