This is due to insufficient input sanitization and output escaping in the acym_cleanVar() sanitizer, whose HTML-tag stripper only matches complete tags (requiring a closing '>'), together with SubscriberInsertion::replaceUserInformation() and the archive view template, which substitute the stored subscriber field value into the mail body and emit it without HTML encoding. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the online-archive URL for the poisoned subscriber, including administrators who click the plugin-generated link in the Subscribers → History screen.","state":0,"publishedAt":"2026-10-13T07:46:23.207+00:00","modifiedAt":"2026-10-15T16:43:51.862+00:00","affected":[{"ecosystem":"Vendor product","name":"AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"acyba\",\n                    \"product\": \"AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"11.1.0\",\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/eb8f03fb-d1af-4727-87d7-58dbe4013d8a?source=cve","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/front/FrontViews/Archive/tmpl/view.php#L17","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/back/dynamics/subscriber/SubscriberInsertion.php#L159","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/back/Classes/FieldClass.php#L292","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/back/Core/wordpress/security.php#L122","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/back/Classes/UserClass.php#L1187","https://plugins.trac.wordpress.org/browser/acymailing/tags/11.1.0/front/FrontControllers/FrontusersController.php#L69","https://plugins.trac.wordpress.org/changeset?reponame=&old=3729031%40acymailing&new=3729031%40acymailing"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102562","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102562","identifiers":["CVE-2026-102562"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
