Official description

OpenClaw is a personal AI assistant. In versions 2026.2.13 and below of the OpenClaw CLI, the process cleanup uses system-wide process enumeration and pattern matching to terminate processes without verifying if they are owned by the current OpenClaw process. On shared hosts, unrelated processes can be terminated if they match the pattern. The CLI runner cleanup helpers can kill processes matched by command-line patterns without validating process ownership. This issue has been fixed in version 2026.2.14.
