The Social Auto Poster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘mapTypes’ parameter in the 'wpw_auto_poster_map_wordpress_post_type' AJAX function in all versions up to, and including, 5.3.14 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

  • A successful exploitation response returns HTTP 200 with a JSON body containing '{"status":"success"}' and Content-Type text/html; monitor for this pattern following requests with XSS payloads in mapTypes.
  • The vulnerability is exploitable by unauthenticated attackers; monitor for AJAX requests to wpw_auto_poster_map_wordpress_post_type without valid authentication cookies.
  • Check for the presence of injected script content (e.g., alert(document.domain)) in the body of /wp-admin/admin.php?page=wpw-auto-poster-settings as an indicator of a successful stored XSS injection.
  • Monitor for the wordpress_logged_in cookie being set after login (HTTP 302 with 'wordpress_logged_in' in the header) as part of a multi-step exploitation chain targeting this vulnerability.
  • ·The vulnerability affects all versions of the Social Auto Poster plugin up to and including 5.3.14; ensure version scope is confirmed before applying detections.
