CVE-2026-66918

pivotick

Pivotick fails to sanitize attacker-controlled SVG markup supplied through the per-node style.svgIcon property before inserting it into the document.

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 Pi...
