Description
The Classified Listing – AI-Powered Classified ads & Business Directory plugin for WordPress is vulnerable to Arbitrary Shortcode Execution via the listing description submitted through the rtcl_post_new_listing AJAX action in all versions up to, and including, 6.1.5. This is due to an inverted capability check in the Functions::sanitize() routine, which removed shortcodes only for editors and kept them for every other non-administrator user, before the description is saved as the listing content and later rendered through the 'the_content' filter. This makes it possible for authenticated attackers with subscriber-level access and above, and unauthenticated attackers when guest listing submission is enabled, to run arbitrary shortcodes.
