This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the attacker's user account to have a mapped author term, which occurs when an administrator has assigned them as a co-author on content or has enabled automatic author term creation for their role \u2014 this mapping is not present by default for new users on a stock install."}], "lastModified": "2026-10-31T08:16:48.463", "sourceIdentifier": "security@wordfence.com"}
