- Severity: CVSS 4.9 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N

## Affected

- rainbowgeek SEOPress – AI SEO Plugin & On-site SEO: through 10.2

## Description

The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'seopress_google_analytics_matomo_id' parameter in all versions up to, and including, 10.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have delegated the Analytics management capability to the Subscriber role via the plugin's Advanced > Security settings.
