 "title": "Custom Post Types and Custom Fields creator – WCK <= 2.4.0 - Authenticated (Subscriber+) Missing Authorization to Post Meta Update via wck_sync_translation AJAX Action",
 "description": "The WCK plugin for WordPress is vulnerable to unauthorized modification of data via the wck_sync_translation AJAX action in all versions up to, and including, 2.4.0, due to a missing capability check and missing nonce verification in the wck_sync_translation_ajax function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to rebuild and overwrite serialized WCK post meta on arbitrary posts that have legacy 'wckwpml_' translation custom fields.",
