CVE-2026-115193 · Severity: high · CVSS 8.2 · Published 2026-10-26

Mautic is a marketing automation platform that manages customer contacts and campaigns. A stored cross-site scripting (XSS) vulnerability in the contact detail view allows attackers to inject malicious scripts into custom contact fields, which then execute when administrators or other users view the affected contact. An attacker exploiting this could create unauthorized admin accounts, modify system configuration, or steal sensitive contact and campaign data.

## Technical details

Mautic 7 renders values of HTML-type custom contact fields without output sanitization in the contact detail view, allowing stored XSS injection. Attackers with contact creation or editing permissions (or via API/form submission) can inject script payloads that execute in the browser context of any user—including administrators—who views the contact. The vulnerability affects Mautic 7.0.0 through 7.2.1, with Mautic 6.x, 5.x, and 4.x unaffected due to proper HTML escaping.
