A CMS user with limited access to pages could copy a page they don't have access to to an area of the site they do. Once copied, they'd be able to view its contents, and potentially publish it. Permissions were correctly checked for the copy destination, but not for the source page.
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.
No workaround is available.
Wagtail thanks independent security researcher Sanjok Karki @thesanjok for reporting this issue.
