CVE-2026-73509: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in OpenListTeam OpenListCVE-2026-73509 0 OpenList a file list program that supports multiple storage. Prior to 4.2.4, the authenticated /api/fs/batch_rename handler in server/handles/fsbatch.go authorizes only the source directory produced by user.JoinPath(req.SrcDir) and validates renameObject.NewName with checkRelativePath, but does not validate attacker-controlled renameObject.SrcName, supplied as src_name, before concatenating it with the authorized path and passing the result to fs.Rename. A user with rename permission can use traversal segments in src_name to make path normalization select a file outside the authorized directory and configured base path, resulting in cross-user file integrity loss, limited availability impact, and file-existence disclosure through success or error responses. This issue is fixed in version 4.2.4. Join the discussion | CVE Database V5 | 08/13/2026, 14:31:05 UTC Added: 08/13/2026, 15:12:13 UTC |
