WordPress · Tutor Lms · CVE-2026-89081
**Name of the Vulnerable Software and Affected Versions**
Tutor LMS versions prior to 4.0.9
**Description**
The Tutor LMS plugin for WordPress contains a Reflected Cross-Site Scripting issue caused by insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts into pages by tricking a user into clicking a malicious link. The issue involves the `search` and `back url` parameters.
**Recommendations**
Update the plugin to a version newer than 4.0.8.
Avoid using the `search` and `back url` parameters until the update is applied.
