A missing capability check allows any authenticated user with Subscriber-level or higher privileges to bypass authorization controls and trigger email notifications to admins, instructors, or any site user.

Exploitation is unlikely to be widespread (EPSS <1%) and the vulnerability is not listed in the CISA KEV catalog, indicating no known public exploitation yet.

Since the plugin executes the action without further authorization, the exposure can be leveraged for mass email delivery or targeted phishing campaigns."}}}}, "created": "2026-03-13T09:53:42.493033+00:00", "updated": "2026-03-20T15:36:10.942854+00:00", "vendors": ["thimpress", "thimpress$PRODUCT$learnpress_\u2013_wordpress_lms_plugin_for_create_and_sell_online_courses", "wordpress", "wordpress$PRODUCT$wordpress"]}
