CVE-2025-15093Public exploitNetwork attack vector

Script execution via unencoded redirectUrl reflection

Published Dec 26, 2025 · Updated Dec 26, 2025

Reflected XSS in FlyCms abbaa5a8daefb146ad4d61027035026b052cb414 allows remote attackers to execute script via redirectUrl. The adminLogin method in IndexAdminController adds the unencoded redirectUrl request parameter to the login-page model, which reflects it into the response. No authentication is required, but a user must request the crafted URL; injected script then runs in that user’s browser context and can alter displayed content.
