This is due to insufficient input sanitization and output escaping on the pma_api_key and pma_sender_address parameters. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the settings page."}], "lastModified": "2026-02-19T15:53:02.850", "sourceIdentifier": "security@wordfence.com"}
