SEOPress: Stored XSS through delegated Matomo settings

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.

CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Oct 03, 2026 and is one of 8 known issues for this plugin.

What to do

Update, patch or deactivate.

The official author release notes confirm remediation by 10.3; this does not establish that every intervening release was affected. Update the affected edition to 10.3 or a later maintained release on its supported branch. Disable the affected feature or component until the update is installed. An application-level fix should validate the Matomo identifier and escape it in its final output context. Remove Analytics management delegation to untrusted roles until updated. Official author release notes: https://wordpress.org/plugins/wp-seopress/.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
