CyberRota Analysis
AI-GeneratedFlowintel versions prior to 3.3.0 are vulnerable due to improper handling of attacker-controlled MISP object fields, which can lead to cross-site scripting (XSS) vulnerabilities when these fields are concatenated directly into HTML. Although DOMPurify mitigates some XSS vectors, it does not fully sanitize all HTML elements, potentially allowing for exploitation. Organizations using affected versions should prioritize patching to safeguard against potential XSS attacks.

Original NVD Description
Affected versions of Flowintel construct timeline HTML using attacker-controllable MISP object fields such as: * object UUID; * object name; * attribute value; * attribute type; * comment; * first/last seen values; * IDS flag. Those values were concatenated directly into HTML strings before rendering. The upstream commit explicitly states that DOMPurify removed XSS vectors but still allowed other HTML elements, such as forms, through. The fix replaces direct string interpolation with DOM construction via document.createElement() and assigns all attacker-controlled values using textContent. The headline is similarly converted to escaped HTML through a temporary element. Version impacted =>3.3.0
