CVE-2026-22708 PUBLISHED

Cursor has a Terminal Tool Allowlist Bypass via Environment Variables

Assigner: GitHub_M
Reserved: 08.01.2026 Published: 14.01.2026 Updated: 14.01.2026

Cursor is a code editor built for programming with AI. Prior to 2.3, hen the Cursor Agent is running in Auto-Run Mode with Allowlist mode enabled, certain shell built-ins can still be executed without appearing in the allowlist and without requiring user approval. This allows an attacker via indirect or direct prompt injection to poison the shell environment by setting, modifying, or removing environment variables that influence trusted commands. This vulnerability is fixed in 2.3.
