# MasterStudy LMS WordPress plugin: stored XSS through script tags in pages

Link for people: https://infrastack.ai/live/CVE-2026-119478 (this .md is for agents)

The MasterStudy LMS WordPress plugin does not neutralize script-related HTML tags in a web page, so injected markup can run in a visitor's browser. An attacker who can get such content into the site can run JavaScript under the context of other users, including staff.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed MasterStudy LMS plugin version in the WordPress admin plugin list or the plugin header in `masterstudy-lms-learning-management-system/` against the affected range through 3.7.56.

## Fix
