AI Powered Q&A
Can you explain this vulnerability to me?
OpenClaw versions prior to 2026.2.13 have a vulnerability in their browser control API. This vulnerability occurs because the API accepts user-supplied output paths for trace and download files without properly restricting these writes to temporary directories.
Attackers who have access to the API can exploit this by using path traversal techniques in specific endpoints (POST /trace/stop, POST /wait/download, and POST /download) to write files outside of the intended temporary directories.
How can this vulnerability impact me? :
This vulnerability allows attackers to write files to arbitrary locations on the system outside of the intended temporary directories.
Such unauthorized file writes can lead to potential security risks such as overwriting critical files, placing malicious files, or otherwise compromising the integrity of the system.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
