Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Wagtail versions before 7.0.9, from 7.1 before 7.3.4, from 7.4 before 7.4.3, and 8.0rc1 are vulnerable. A CMS user who has "add" permission on a snippet model but not "change" or "view" permission can copy an existing snippet they should not access and so view its contents. Upgrade to Wagtail 7.0.9, 7.3.4, 7.4.3, 8.0rc2 or later. No workaround is listed.
