This is a followup advisory to SA-CONTRIB-2026-245 [3], which did not fully resolve the underlying vulnerability. In some cases, files may be served with the HTTP header Cache-Control: public when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. This vulnerability is mitigated by the following: * Drupal must be configured to handle non-public files using a custom or contributed module providing an additional file scheme. * An attacker must know to request a file that has previously been requested by a more-privileged user, and that file must still be cached. Solution:  Install the latest version: * If you use version 3.0.x, upgrade to 3.0.3 [4]. * If you use version 2.1.x, upgrade to 2.1.3 [5].
