AI-analyzed exploit summary Detailed technical analysis of CVE-2026-9809, a Stored XSS vulnerability in Mautic 7.0.0-7.1.1. The writeup explains the root cause (improper output sanitization in project tags/popovers), attack flow, and includes conceptual vulnerable/corrected code snippets without providing functional exploit code.

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.
