      "title": "Improper Restriction of Excessive Authentication Attempts vulnerability in CIRCL Vulnerability-Lookup",
      "summary": "In affected versions, vulnerability-lookup did not track or limit failed\n One-Time Password (OTP) attempts during Two-Factor Authentication (2FA)\n verification. An attacker who already knew or guessed a valid username \nand password could submit an arbitrary number of OTP codes without \ncausing the account to be locked or generating any specific alert for \nadministrators.\n\n\nThis lack of rate-limiting and lockout on OTP failures significantly \nlowers the cost of online brute-force attacks against 2FA codes and \nincreases the risk of successful account takeover, especially if OTP \nentropy is reduced (e.g. short numeric codes, user reuse, or predictable\n tokens). Additionally, administrators had no direct visibility into \naccounts experiencing repeated 2FA failures, making targeted attacks \nharder to detect and investigate.\n\n\nThe patch introduces a persistent failed_otp_attempts counter on user \naccounts, locks the user after 5 invalid OTP submissions, resets the \ncounter on successful verification, and surfaces failed 2FA attempts in \nthe admin user list. This enforces an account lockout policy for OTP \nbrute-force attempts and improves monitoring capabilities for suspicious\n 2FA activity.This issue affects Vulnerability-Lookup: before 2.18.0.",
