The DT LMS – elearning WordPress plugin allows unauthenticated attackers to modify arbitrary plugin option values in the `wp options` table. This is caused by a missing capability check and lack of nonce verification in multiple AJAX handlers, including `dtlms save poc settings`, `dtlms save skin settings`, and `dtlms save options settings`. These handlers are registered on the `wp ajax nopriv *` hook and pass user-supplied data directly to the `update option()` function. An attacker can exploit this to overwrite Point-of-Contact email configurations and skin or branding settings, altering the appearance and behavior of the LMS for all visitors.
