CVE-2025-0281Public exploitNetwork attack vector

Stored XSS via unsanitized SAML redirect URL

Published Mar 20, 2025 · Updated Mar 20, 2025

Stored XSS in Lunary before 1.7.10 allows remote authenticated users to execute JavaScript through malicious SAML IdP metadata. The SAML login flow derives a redirect URL from attacker-controlled XML metadata and assigns it to window.location.href without validating or sanitizing the URL. An account able to configure SAML metadata and a user who follows the generated login redirect are required, exposing the victim's session and page data to script access.
