Wagtail has improper permission handling when viewing page history

Impact

A CMS user without the ability to edit a page could still access the history report for the page, potentially resulting 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.
