The DAV plugin resolves files from the absolute request URI without verifying that the path segment matches the authenticated session user. This enables:</p> <p>Cross-user manual locks : attacker locks a victim&#39;s files, blocking writes (PUT/MOVE/DELETE, editor saves). Lock-token disclosure: the app returns the lock token to unauthorized callers, enabling them to remove token-based locks (client locks) of other users.</p> <p><strong>Affected:</strong> Nextcloud Files Lock</p> <p>Any authenticated user can lock or unlock files they do not own by targeting absolute WebDAV paths of other users.
