Add comprehensive security controls to reset-password endpoint, including CAPTCHA, secure token with TTL, account lockout, dummy cookie, security question, post-reset session termination, and user notification.

[zeropath-ai-dev]

Summary

• The Vulnerability Description:
  The /rest/user/reset-password endpoint previously lacked essential security protections, making it susceptible to automated abuse, user enumeration, insecure reset tokens, brute-force attacks on security questions, and failing to terminate active sessions or notify users after a password reset.

• This Fix:
  The patch fortifies the reset-password process by adding CAPTCHA verification, generating secure tokens with time-to-live (TTL), including a dummy cookie to mitigate user enumeration, enforcing security-question checks with account lockout on repeated failures, and ensuring session termination with user notifications after a successful reset.

• The Cause of the Issue:
  The vulnerability stemmed from insufficient implementation of industry-standard security controls in the reset-password flow, leaving multiple attack surfaces exposed during the password recovery process.

• The Patch Implementation:
  The update introduces several middleware layers: CAPTCHA enforcement, secure token creation with TTL and storage, dummy cookie placement on reset attempts, robust security question validation with lockout after repeated failures, and a post-reset module to terminate existing sessions and notify users, significantly improving endpoint security.
