Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in The Wikimedia Foundation Mediawiki - CSS Extension allows Path Traversal.This issue affects Mediawiki - CSS Extension: from 1.42.X before 1.42.2, from 1.41.X before 1.41.3, from 1.39.X before 1.39.9.
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.
