CVE-2022-29174Network attack vector

Account takeover via predictable password reset token

Published May 17, 2022 · Updated Apr 23, 2025

Weak password recovery in Countly Server before 21.11.4 and 22.0.0 through 22.03.6 allows remote attackers to take over accounts. The forgot handler in frontend/express/libs/members.js derives each reset token by hashing the stored username and full name with a timestamp rather than using random bytes. An attacker must know an account's email address or username and full name; guessing the token permits a password reset and control of that account.
