Detailsinfo

A vulnerability was found in librsvg up to 2.56.2. It has been classified as critical. This affects an unknown part of the component URL Decoder. The manipulation of the argument href 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. This is going to have an impact on confidentiality. The summary by CVE is:

A directory traversal problem in the URL decoder of librsvg before 2.56.3 could be used by local or remote attackers to disclose files (on the local filesystem outside of the expected area), as demonstrated by href=".?../../../../../../../../../../etc/passwd" in an xi:include element.
