CVE-2026-75933Network attack vector

Stored XSS via sign-in customization

Published Aug 21, 2026 · Updated Aug 21, 2026

Stored XSS in the sign-in page of Jet Admin allows remote authenticated users to execute JavaScript in visiting users' domains. The Scripts & Styles setting accepts and stores attacker-supplied JavaScript, which the sign-in page renders without neutralizing executable content. Access to sign-in customization and a subsequent page visit are required; execution can expose or alter data available to the visitor's browser context.
