The curationDraft() function only verifies current_user_can('read') without checking whether the user has edit_post permission for the target post. Combined with the plugin granting UI access and nonce exposure to all roles, this makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the title and content of arbitrary posts and pages by supplying a target post ID via the 'b2s-draft-id' parameter."}], "lastModified": "2026-02-18T17:51:53.510", "sourceIdentifier": "security@wordfence.com"}
