Summary
An unauthenticated improper input validation vulnerability in the POST /fetch_cve_data endpoint in cve-search. A remote attacker can manipulate request parameters controlling the MongoDB collection, projected fields, and regular-expression filters to read arbitrary application MongoDB collections. This can expose administrative usernames and password hashes from the mgmt_users collection, enabling offline password cracking and potential administrative account compromise.
