EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 72% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
