What an attacker needs
- Access: A low-level account on the site, such as a subscriber or customer (per the CVSS score).
CVSS vector (score by CISA ADP): CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
What to do now
- Replace Academy LMS. A closed plugin gets no updates through WordPress, so this hole stays open.
- Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deactivating alone leaves its files on the server.
- Not sure which version you run? Check your version against every known Academy LMS issue.
- If you ran an affected version and something looks off (new admin users, spam pages, redirects), run the free scan below.
The advisory
The Academy LMS WordPress plugin before 4.0.0 does not verify that a quiz question belongs to the course the requesting user is authorized to access before returning that question's answer options, allowing any authenticated user with access to a single course, such as an enrolled student, to read the quiz answer options of questions belonging to other courses they are not enrolled in.
