# Meta Box WordPress plugin: stored XSS through custom fields framework

Link for people: https://infrastack.ai/live/CVE-2026-123472 (this .md is for agents)

Meta Box, a WordPress custom fields framework, does not neutralize input properly, so stored cross-site scripting is possible. An attacker who can get a malicious value saved can run script in the browser of anyone who later views the affected page.

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

## How to check

- Check whether the Meta Box plugin is installed and its version in the WordPress admin under Plugins.
- Compare the installed version against `5.15.3`; versions through `5.15.3` are listed as affected.
