Cross-user file access and deletion via path traversal
Published Feb 2, 2026 · Updated Feb 2, 2026
Path traversal in OpenList before 4.1.10 allows remote authenticated users to read, copy, rename, or delete other users' files. The FsCopy and FsRemove handlers in server/handles/fsmanage.go pass req.Names values to stdpath.Join after validating only the directory, so .. segments escape the user's base path. Exploitation requires basic copy or remove permission, a shared storage mount, and knowledge or a guess of the target path.
