CVE-2025-26524Network attack vector

OTP flooding via unthrottled request endpoints

Published Feb 14, 2025 · Updated Feb 14, 2025

Improper interaction-frequency control in RupeeWeb before 66.9 allows remote authenticated users to flood targets with OTP requests. Certain OTP-request API endpoints accept repeated submissions without enforcing a request-frequency limit. Valid credentials and network access to those endpoints are required; exploitation burdens the targeted system with repeated OTP traffic.
