Directorist 3.1.0 - 8.9.4 - Subscriber+ Arbitrary Listing Deletion via remove_listing

Description

The plugin does not properly verify a listing's ownership before deleting it, allowing 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.
