Detailed vulnerability description
The vulnerability allows a remote user to bypass authorization or policy checks.
The vulnerability exists due to improper link resolution before file access in the OpenShell mirror sync feature when processing a configured input path containing remote symlink parents. A remote user can provide a crafted input path to bypass authorization or policy checks.
Only instances where the affected feature is enabled and reachable are vulnerable, and practical impact depends on whether lower-trust input can reach that path.
