The payload is delivered by submitting a Contact Form 7 request with a nested POST array key containing arbitrary HTML or JavaScript \u2014 PHP parses the field name into a nested array key, which is stored verbatim in the zerospam_log.submission_data column when Zero Spam flags the submission as spam due to the absence of the zerospam_david_walsh_key field."}], "lastModified": "2026-09-25T13:08:08.163", "sourceIdentifier": "security@wordfence.com"}
