Detailsinfo

A vulnerability classified as critical has been found in allegroai clearml up to 2.0.1. Affected is the function safe_extract of the component Symbolic Link Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
