Description
The GEO Plugin by Squirrly SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the custom Facebook Pixel code field of a page's SEO settings in all versions up to, and including, 14.2.6. This is due to the field keeping <script> tags for any user able to edit a post, regardless of the unfiltered_html capability, and the value being printed unescaped in the page head when the plugin's Facebook Pixel feature is enabled. This makes it possible for authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
