This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the BCC field of the acy_notification_cms notification template, causing subsequent WordPress password-reset emails — including those targeting administrator accounts — to be silently copied to an attacker-controlled address, enabling account takeover via the captured reset link. Successful exploitation requires the site administrator to have enabled the \"Send website emails with AcyMailing\" option, which routes WordPress core notification emails through AcyMailing's templating system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress","id":"CVE-2026-15426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"OS Command Injection in TR-069 (CWMP) Management Interface in TP-Link Archer VX1800v","id":"CVE-2026-15427"},"packages":[],"prev":{"headline":"Yoast SEO \u003c= 28.0 - Authenticated (Author+) Stored Cross-Site Scripting via Post Slug (post_name)","id":"CVE-2026-15425"},"products":["AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress"],"published":"2026-08-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["acyba"]},"summary":"Authenticated subscribers can overwrite notification templates to capture password reset links, enabling account takeover if specific email routing is enabled.","url":"https://insights.sbomify.com/CVE-2026-15426/"}
