Client-side script execution via unvalidated login redirect

Published May 26, 2026 · Updated May 26, 2026

DOM-based cross-site scripting in Teable 1.0 through 1.9 allows remote attackers to execute script via a crafted login redirect. LoginPage.tsx passes the untrusted redirect parameter to client-side navigation without validating its scheme or origin, permitting javascript: and data: destinations. A victim must open the crafted URL and complete the affected login flow; successful exploitation can alter data through the victim's browser session.
