Detailsinfo

A vulnerability classified as critical was found in OpenListTeam OpenList up to 4.1.9. Affected by this vulnerability is an unknown functionality of the file server/handles/fsmanage.go. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

OpenList Frontend is a UI component for OpenList. Prior to 4.1.10, the application contains path traversal vulnerability in multiple file operation handlers in server/handles/fsmanage.go. Filename components in req.Names are directly concatenated with validated directories using stdpath.Join. This allows ".." sequences to bypass path restrictions, enabling users to access other users' files within the same storage mount and perform unauthorized actions such as deletion, renaming, or copying of files. An authenticated attacker can bypass directory-level authorisation by injecting traversal sequences into filename components, enabling unauthorised file removal and copying across user boundaries within the same storage mount. This vulnerability is fixed in 4.1.10.
