Unauthenticated settings overwrite via unguarded AJAX handlers
Published Sep 12, 2026 · Updated Sep 12, 2026
Missing authorization in DesignThemes DT LMS 1.1 and earlier allows remote attackers to overwrite plugin settings through AJAX requests. The dtlms_save_poc_settings, dtlms_save_skin_settings, and dtlms_save_options_settings handlers accept untrusted data and pass it to update_option() without capability or nonce checks. No account is required, and successful requests alter LMS email, branding, or behavioral settings for all site visitors.
