AI-suggested

If you cannot patch yet, administrators should consider restricting access to authenticated users and implement additional protective measures such as CSRF protections or disabling the vulnerable AJAX action if possible.

Description

The Solace Extra WordPress plugin before 1.6.1 does not perform capability or nonce checks in one of its AJAX actions, allowing any authenticated user such as a subscriber (and, via CSRF, any logged-in user) to update post meta on arbitrary posts and to deactivate the site's active templates.
