# WordPress Gallery PhotoBlocks plugin: stored XSS through 1.3.7

The Gallery PhotoBlocks WordPress plugin by WP Chill does not neutralize input when generating pages, so stored cross-site scripting is possible. An attacker with rights to add content can plant script that runs in other visitors' browsers.

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

## How to check

- Check the installed version of photoblocks-grid-gallery in the WordPress plugins screen or `wp plugin get photoblocks-grid-gallery --field=version`
- Confirm whether the plugin is active on any site

## Fix

- Update photoblocks-grid-gallery to a version later than `1.3.7`, if one is released; the sources do not name a fixed version
- Until patched, deactivate the plugin or restrict contributor-level accounts
