CVE-2026-110176
File Force Download for Drupal 7 Access Bypass via Unconditional Download Headers
The File Force Download module for Drupal 7 implements hook_file_download() to add a Content-Disposition header when a file URL carries the download query parameter. In Drupal 7, returning a non-empty header array from that hook is itself a grant of access to the file. In versions 7.1.0 through 7.1.2, the module only delegated to other modules' hook_file_download() implementations when the file was in the private scheme. For every other scheme it returned its headers without any check. An unauthenticated visitor who appended download=1 to the URL of a file in the temporary:// scheme, or in a stream wrapper supplied by another module, could retrieve the file, overriding the access checks that would otherwise have applied. Files in the public and private schemes are not affected.
Fixes and workarounds
Workaround
Disable the File Force Download module, avoid keeping sensitive files in the temporary:// scheme or in stream wrappers provided by contributed modules, or block anonymous requests that carry a download parameter at the web server or WAF.
