not scored yet plugin closed published 2026-11-03

Affected versions: 1.2 and older
Fixed in: unknown
Severity: Not scored yet
Active installs: closed
Type: Security issue

What an attacker needs

Access: None. No account or login is needed.

What to do now

Replace DT 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 DT 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 DT LMS WordPress plugin through 1.2 does not perform capability or nonce checks on one of its AJAX actions, allowing unauthenticated attackers to revoke any learner's course and class completion status.
