CVE-2026-66918
DOM-Based Cross-Site Scripting via Unsanitized SVG Node Icons
Description
Pivotick fails to sanitize attacker-controlled SVG markup supplied through the per-node style.svgIcon property before inserting it into the document. When rendering a graph node, the vulnerable code assigns the SVG icon markup directly to the innerHTML property of a live SVG element. An attacker able to influence graph data can provide crafted markup containing executable event handlers, such as an <image> element with an onerror attribute. When a victim loads or renders the malicious graph, the payload may execute arbitrary JavaScript in the security context of the application embedding Pivotick. Successful exploitation could allow the attacker to access application data available to the victim, modify displayed content, or perform actions using the victim’s authenticated session. Exploitation requires an application using Pivotick to render graph data that is controlled or modified by an attacker.
