Last modified

CVE-2026-22708 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. 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. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
