This is due to insufficient authorization and input sanitization in the send_test_mail() function, which allows user-controlled PHP code to be written to executable files in the uploads directory. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary PHP code on the server, leading to full site compromise.","state":0,"publishedAt":"2026-10-15T06:41:59.561+00:00","modifiedAt":"2026-10-15T16:43:40.115+00:00","affected":[{"ecosystem":"Vendor product","name":"Email Customizer for WooCommerce (Pro)","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ThemeHigh\",\n                    \"product\": \"Email Customizer for WooCommerce (Pro)\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.9.5\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e8d4cd3d-68ad-45ec-b4b3-e705da4e6628?source=cve","https://www.themehigh.com/changelog/?view=22"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-81534","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-81534","identifiers":["CVE-2026-81534"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
