    DRUPAL-CONTRIB-2026-292

    Published: 28 Oct 2026Last Modified: 28 Oct 2026

    Summary:

    Details: This module allows for direct viewing of a file with the URL alias. This is a followup advisory to [SA-CONTRIB-2026-245](https://www.drupal.org/sa-contrib-2026-245), 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.
