CVE-2026-90602Public exploitNetwork attack vector

Script execution via unescaped history attributes

Published Sep 13, 2026 · Updated Sep 13, 2026

DOM-based XSS in Open Generative AI 1.0.0 through 1.0.11 and 2.0.0 allows attackers to execute script via poisoned studio history. ImageStudio.js renderHistory inserts localStorage URL and prompt values into an innerHTML template without escaping, permitting attribute breakout and event-handler injection. The script runs when a crafted history entry is rendered on page load and can read data accessible to the application origin.
