What the vulnerability does
01Description
The ZoomSounds - WordPress Wave Audio Player with Playlist plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the 'dzsap_delete_notice' AJAX action in all versions up to, and including, 6.91. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to 'seen' on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny service to legitimate users or be used to set some values to true such as registration. There are several other functions also vulnerable to missing authorization.
Explanation of Vulnerability in Simple Terms
02Summary
ZoomSounds WordPress plugin versions 6.91 and earlier lack proper authorization checks, allowing authenticated users to modify or delete audio content and playlists they should not have access to. An attacker with a low-privilege account can escalate their capabilities within the plugin without additional user interaction. Site administrators should update immediately to a version newer than 6.91.
