Account takeover via predictable password-reset links

Published Nov 10, 2025 · Updated Nov 10, 2025

Weak password recovery in Hundred Plus EIP Plus before RELEASE_240626 allows remote attackers to reset any user's password. The recovery flow returns a reset link in specific response packets, while the link value is predictable or susceptible to brute force. No authentication or user interaction is required, and a successful reset grants access to the target account.
