This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is delivered by submitting a Contact Form 7 request with a nested POST array key containing arbitrary HTML or JavaScript — 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.","state":0,"publishedAt":"2026-09-25T07:40:23.949+00:00","modifiedAt":"2026-09-25T10:34:21.815+00:00","affected":[{"ecosystem":"Vendor product","name":"Zero Spam for WordPress","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"bmarshall511\",\n                    \"product\": \"Zero Spam for WordPress\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.7.10\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/01540d78-ae46-4556-9a7f-3f8b8dbbcbd7?source=cve","https://plugins.trac.wordpress.org/browser/zero-spam/tags/5.7.10/includes/templates/admin-modal-details.php#L200","https://plugins.trac.wordpress.org/browser/zero-spam/tags/5.7.10/modules/contactform7/class-contactform7.php#L85","https://plugins.trac.wordpress.org/browser/zero-spam/tags/5.7.10/core/class-utilities.php#L65","https://plugins.trac.wordpress.org/browser/zero-spam/tags/5.7.10/includes/class-db.php#L442","https://plugins.trac.wordpress.org/changeset?reponame=&old=3709762%40zero-spam&new=3709762%40zero-spam"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96752","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96752","identifiers":["CVE-2026-96752"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
