Lifecycle Timeline
4Description
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.
Analysis
Command injection in OpenClaw versions before 2026.2.19 allows local attackers with limited privileges to execute arbitrary commands when the Lobster extension tool falls back to Windows shell execution after subprocess failures. The vulnerability exists because the tool uses shell: true after spawn errors, enabling attackers to inject shell metacharacters into command arguments. …
