Directorist WordPress plugin vulnerabilities

The Directorist WordPress plugin before 8.9.5 does not verify that the target user of a REST route matches the authenticated caller before reading and modifying that user's saved favorites. This allows any authenticated user with subscriber-level access to view and alter another user's favorites.

The Directorist WordPress plugin before 8.9.5 does not properly verify a listing's ownership before deleting it. This allows authenticated attackers with Subscriber-level access and above to delete arbitrary listings, including ones belonging to other users. This is an incomplete fix of CVE-2023-1889 / CVE-2023-35052: a separate, unaddressed listing-deletion path allows the same impact, from at least version 3.1.0 through the current release.

The Directorist WordPress plugin before 8.9.5 does not validate a user-supplied URL before fetching it server-side. This allows users with the subscriber role and above to make the server issue requests to internal addresses.
