CVE-2026-101357: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in rainbowgeek SEOPress – AI SEO Plugin & On-site SEO
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.
AI Analysis
Technical Summary
CVE-2026-101357 describes a stored cross-site scripting vulnerability in the SEOPress – AI SEO Plugin & On-site SEO WordPress plugin. The flaw exists in the handling of the 'seopress_google_analytics_matomo_id' parameter, allowing authenticated users with subscriber-level privileges or above to inject arbitrary scripts. This requires that the administrator has delegated Analytics management capability to the Subscriber role via the plugin's Advanced > Security settings. The vulnerability affects all versions up to and including 10.2 and is due to improper neutralization of input during web page generation (CWE-79).
Potential Impact
An attacker with subscriber-level access or higher can inject persistent malicious scripts that execute in the context of users visiting the affected pages. This can lead to limited confidentiality and integrity impacts, such as theft of user data or session tokens. The attack requires specific administrative configuration (delegation of Analytics management to subscribers) and does not affect unauthenticated users.
Mitigation Recommendations
No official patch or fix is currently documented. Administrators should avoid delegating Analytics management capability to subscriber roles to prevent exploitation. Monitor vendor advisories for updates or patches addressing this vulnerability.
