CVE-2026-9809 Details
Description
A stored Cross-Site Scripting (XSS) vulnerability exists in the Projects component of Mautic 7. When displaying project tags and popovers on administrative detail views (such as campaigns, emails, or forms), user-supplied project names are rendered without proper sanitization. An authenticated user with permissions to create or edit projects can exploit this to inject malicious script payloads. When an administrative user views an entity associated with a compromised project and hovers over its tag, the injected script executes within the context of their active browser session. This could allow an attacker to perform administrative actions on behalf of the victim, alter system configurations, or exfiltrate sensitive data.
A stored Cross-Site Scripting (XSS) vulnerability has been identified in the Projects component of Mautic version 7. This issue arises because user-supplied project names are displayed without adequate sanitization in administrative detail views, such as campaigns, emails, or forms. An authenticated user with the ability to create or edit projects can exploit this vulnerability by injecting malicious script payloads. When an administrative user interacts with an entity linked to the compromised project, the injected script executes in their browser session. This could enable the attacker to perform actions on behalf of the victim, modify system settings, or steal sensitive information.
Users can upgrade to Mautic version 7.1.2 to address this vulnerability. For those using earlier versions of Mautic 7, it is recommended to restrict project creation and editing permissions to trusted administrative users.
