Medium (5.8) in openclaw openclaw. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.19.
OpenClaw versions prior to 2026.2.19 contain a command injection vulnerability in the Lobster extension tool execution that uses Windows shell fallback with shell: true after spawn failures. Attackers can inject shell metacharacters in command arguments to execute arbitrary commands when subprocess launch fails with EINVAL or ENOENT errors.
