Detailsinfo

A vulnerability classified as problematic has been found in rainbowgeek SEOPress Plugin up to 10.3. Affected is the function seopress_google_analytics_js of the file inc/admin/sanitize/Sanitize.php of the component Setting Handler. The manipulation of the argument seopress_google_analytics_affiliate_tracking/seopress_google_analytics_download_tracking with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. CVE summarizes:

The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'seopress_google_analytics_affiliate_tracking' and 'seopress_google_analytics_download_tracking' settings in versions up to, and including, 10.3. This is due to insufficient input sanitization and output escaping on these settings as they are interpolated into the inline Google Analytics tracking snippet by seopress_google_analytics_js(): the affiliate value receives no sanitization at all (it is omitted from inc/admin/sanitize/Sanitize.php) and lands inside a <script> block, while the download value is only passed through sanitize_text_field() and lands inside a JavaScript regular-expression literal that preserves parentheses, semicolons and slashes. This makes it possible for authenticated attackers, with Subscriber-level access and above (where an administrator has delegated the SEOPress 'analytics' capability under Settings > Advanced > Security — the precondition Wordfence accepted for CVE-2026-101357), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-120515 since 11/02/2026. The exploitability is told to be easy.
