CVE-2023-47623Public exploitNetwork attack vector

Post-login script execution via unchecked redirect URI

Published Dec 13, 2023 · Updated Aug 2, 2024

Reflected XSS in the Scrypted 0.55.0 and earlier login page allows remote attackers to execute JavaScript through a crafted link. Login.vue reads redirect_uri from the page URL and assigns it directly to window.location after login without rejecting the javascript scheme. A victim must open the crafted link and complete login; the injected script then acts through that authenticated session and can issue RPC requests.
