This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires pretty permalinks to be enabled, as the exploit chain depends on get_permalink() embedding the stored percent-encoded post_name in the generated URL."}], "lastModified": "2026-07-27T20:25:13.817", "sourceIdentifier": "security@wordfence.com"}
