CVE-2025-46826Network attack vector

Student-data disclosure via unrestricted CAS redirect

Published May 7, 2025 · Updated May 8, 2025

Open redirect in Genda insa-auth before 2025-05-03 allows remote attackers to expose basic student data through the CAS bridge. The login route uses a caller-provided CAS server endpoint as the redirect destination without restricting the URL. No account is required, but a victim must follow the crafted redirect; the reported disclosure is limited to a student's name and number.
