What is CVE-2026-12273?

The Tutor LMS WordPress plugin prior to version 3.9.13 contains a significant security flaw that allows authenticated users, including those with subscriber-level access and above, to post comments without undergoing the appropriate authorization checks. This vulnerability enables the posting of auto-approved comments that may include arbitrary HTML and links, effectively bypassing the standard comment moderation process. This poses a risk as it allows potential abuse of comments sections across the site, making it crucial for users to update to the latest version to mitigate these risks.

Affected Version(s)

Tutor LMS 0 < 3.9.13
