Description
The WordLift – AI powered SEO – Schema plugin for WordPress is vulnerable to unauthorized modification of data via the 'wl_schemaorg_sync' and 'wl_schemaorg_sync_count' AJAX actions in all versions up to, and including, 3.54.15. The cause is a missing capability check in the Wordlift_Batch_Operation_Ajax_Adapter process() and count() functions. Their only check is a nonce, and that nonce is printed in the wlSettings script data on every admin page for every logged-in user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to run the Schema.org taxonomy sync. The sync overwrites the names, descriptions, parent relationships and metadata of the Entity Types taxonomy terms with the bundled defaults. The handlers are registered only when the 'all entity types' feature is enabled.
