CVE-2025-58361Public exploitNetwork attack vector

Script execution via incomplete URL scheme filtering

Published Sep 4, 2025 · Updated Sep 4, 2025

Cross-site scripting in all versions of Promptcraft Forge Studio allows remote attackers to execute JavaScript via a crafted data URL. The check in src/utils/validation.ts removes javascript and several other patterns but accepts data URLs containing executable SVG. Exploitation requires the crafted value to reach an href or src sink and be clicked or rendered, exposing application-origin data and actions.
