Administrator-triggered read and write access to site data
Published Aug 25, 2026 · Updated Aug 25, 2026
An undisclosed flaw in Drupal Lunr exposed filters affects all versions and allows attackers to read, modify, or delete site data. Drupal has not published the vulnerable component or the operation it performs incorrectly, so the precise request path remains undisclosed. Successful exploitation requires administrator privileges and a complex, multistep path, while every module configuration is affected.
