This is due to a missing capability check in the ajax_save_settings() function, which accepts arbitrary POST parameters and calls update_option() with attacker-controlled keys and values without any authorization verification. This makes it possible for authenticated attackers, with subscriber-level access and above, to elevate their privileges to administrator by setting the default_role WordPress option to 'administrator' and users_can_register to '1', then registering a new account that is automatically granted full administrator access.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794483136143,"publishedAt":1794483136143,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2d754689-0d64-4cb8-9c73-7dd6d4fb0c72?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://my.wishlistmember.com/changelog/coursecure-courses-1-5-3/"}],"remediation":[],"revision":"6e51f39de79c613f9ee6b812c51106ece6402b5846e58a3951c2025bb4dce45f","sources":[{"modifiedAt":1794483136143,"name":"CNA: Wordfence","retrievedAt":1794485385022,"url":"https://www.cve.org/CVERecord?id=CVE-2026-15309"}],"ssvc":null,"status":"published","title":"CourseCure Courses <= 1.5.1 - Authenticated (Subscriber+) Privilege Escalation to 'ajax_save_settings' Endpoint","updatedAt":1794485385022}
