This is due to the plugin registering the 'build-app-online-update-vendor-product' AJAX action via wp_ajax_nopriv_ without proper authentication checks, capability verification, or nonce validation in the update_vendor_product() function. The function accepts a user-supplied post ID from the request and calls wp_update_post() to modify the post_author field without validating whether the user has permission to modify the specified post. This makes it possible for unauthenticated attackers to modify the post_author of arbitrary posts to 0 (orphaning posts from their legitimate authors), or for authenticated attackers to claim ownership of any post by setting themselves as the author."}, {"lang": "es", "value": "El plugin Build App Online para WordPress es vulnerable a acceso no autorizado en todas las versiones hasta la 1.0.23, inclusive. Esto se debe a que el plugin registra la acci\u00f3n AJAX 'build-app-online-update-vendor-product' a trav\u00e9s de wp_ajax_nopriv_ sin las comprobaciones de autenticaci\u00f3n adecuadas, verificaci\u00f3n de capacidades o validaci\u00f3n de nonce en la funci\u00f3n update_vendor_product().

Esto hace posible que atacantes no autenticados modifiquen el post_author de publicaciones arbitrarias a 0 (dejando las publicaciones hu\u00e9rfanas de sus autores leg\u00edtimos), o que atacantes autenticados reclamen la propiedad de cualquier publicaci\u00f3n al establecerse a s\u00ed mismos como el autor."}], "lastModified": "2026-03-23T14:32:02.800", "sourceIdentifier": "security@wordfence.com"}
