CVE-2022-29547
This could lead to an unauthorised (or blocked) user being able to edit a page.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The CreateRedirect extension before 2022-04-14 for MediaWiki does not properly check whether the user has permissions to edit the target page. This could lead to an unauthorised (or blocked) user being able to edit a page.
