Sensitive data disclosure via shared role cache keys
Published Feb 18, 2020 · Updated Aug 6, 2024
Improper access control in Drupal Authcache before 7.x-1.5 allows remote authenticated users to read superuser-only cached page content. The cache-key generator groups responses by role combination without assigning Drupal user 1 a unique key, so another account with every role receives the superuser cache entry. Exploitation requires caching for all roles, an all-role account, a page rule covering all roles, and superuser-only content on a cacheable page.
