high 7.2 CVE-2026-102562 · published 2026-10-13

Stored cross-site scripting (XSS) in AcyMailing (11.1.0 and older)

Affected: 11.1.0 and older
Fixed in: unknown
Access needed (per CVSS): No login needed
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The AcyMailing plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the customField[] parameter of the public frontusers::subscribe endpoint in versions up to, and including, 11.1.0. 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.

Fixed in: 11.0.0 *
Access needed (per CVSS): Needs a low-level account (e.g. subscriber)
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 10.11.1. 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.
