Wagtail has improper permission handling when comparing revisions

  • Disclosed: 08.05.2026
  • Updated: 11.10.2026 12:19

Impact

A CMS user without the ability to edit a page could access revisions of the page through the revision compare view if they knew the primary key of two revisions. This could potentially result in disclosure of sensitive information.

Patches

Patched versions have been released as Wagtail 7.0.7 and 7.3.2. The new 7.4 LTS feature release also incorporates this fix.

Workarounds

No workaround is available.
