AI-analyzed exploit summary Detailed technical analysis of CVE-2026-9811, a Stored XSS vulnerability in Mautic 7.0.0-7.1.1. The writeup explains the root cause (unsanitized project names inserted into DOM via AJAX), attack flow, and provides conceptual vulnerable/corrected code examples without including functional exploit code.

A stored Cross-Site Scripting (XSS) vulnerability exists in the project selector component of Mautic 7. When rendering selection menus for associating projects with system entities, the application fails to sanitize project names returned via AJAX before injecting them into the DOM as option fields. An authenticated user with permissions to create projects can exploit this to store a malicious script payload in the project's name. When another administrative user subsequently opens an entity editor containing the project selector, the injected script executes within the context of their active browser session. This could allow an attacker to hijack the session, perform unauthorized state coordination, or access organizational data within the dashboard.
