# Seriously Simple Podcasting WordPress plugin: stored XSS through version 3.17.0

The Seriously Simple Podcasting WordPress plugin by Castos fails to neutralize input before generating web pages, which allows stored cross-site scripting. An attacker who can get script stored in the plugin's content can run it in the browser of anyone who views the affected page, such as an admin.

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

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or with `wp plugin get seriously-simple-podcasting --field=version`
- Compare against the affected range: versions up to and including `3.17.0`

## Fix

- Update Seriously Simple Podcasting to a version later than `3.17.0`; the sources do not name the fixed version, so check the plugin's changelog
- Until updated, restrict who can add podcast content or episode metadata
