CVE-2025-26522Network attack vector

Authenticated 2FA bypass via manipulated API responses

Published Feb 14, 2025 · Updated Feb 14, 2025

Authentication bypass in RupeeWeb before 66.9 allows remote authenticated users to bypass 2FA for other accounts via API response manipulation. Certain API endpoints trust attacker-modified response data during OTP validation instead of treating that data as untrusted. Valid platform credentials are required, and successful exploitation defeats the second authentication factor protecting another account.
