Description
OpenClaw through 2026.2.22 contains a symlink traversal vulnerability in agents.create and agents.update handlers that use fs.appendFile on IDENTITY.md without symlink containment checks. Attackers with workspace access can plant symlinks to append attacker-controlled content to arbitrary files, enabling remote code execution via crontab injection or unauthorized access via SSH key manipulation.
Analysis
OpenClaw through version 2026.2.22 allows authenticated local attackers to execute arbitrary code or manipulate system files via symlink traversal in the agents.create and agents.update handlers. The vulnerability stems from unsafe use of fs.appendFile on IDENTITY.md without validating symlink targets, permitting attackers with workspace access to plant symlinks pointing to sensitive files like crontab or SSH configuration directories and inject malicious content through the agent creation/update process.
