What to do

Update, patch or deactivate.

No fixed release is identified. Update Tutor LMS – eLearning and online course solution when a release after 3.9.11 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 4.0.5, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via the 'data' parameter in all versions up to, and including, 3.9.11 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
