CVE-2026-67173Network attack vector

Client-side requests via unvalidated node image schemes

Published Jul 28, 2026 · Updated Jul 28, 2026

URL scheme validation failure in Pivotick 1.4.0 and earlier allows attackers to trigger unintended client-side requests via crafted graph data. The NodeDrawer resolves graph-derived nodeStyle.imagePath values and assigns them to SVG images without restricting URI schemes, so rendering fetches a hostile location. A victim must load the crafted graph; consequences are limited to browser-side requests, tracking, metadata exposure, or attempts to reach local or internal resources.
