CVE-2026-103422
highThe AnyComment plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email' parameter in versions up to, and including, 0.3.6.
The AnyComment plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email' parameter in versions up to, and including, 0.3.6. This is due to insufficient input sanitization on the public /wp-json/anycomment/v1/subscribe REST endpoint and missing output escaping in AnyCommentSubscriptionsTable::column_default(), which returns the stored email verbatim into an HTML when the subscription's user_ID does not resolve to an existing WP_User. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the AnyComment → Subscriptions admin page.
