Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Arbitrary MongoDB collection disclosure in cve-search allows a remote, unauthenticated attacker to read any application database collection through the POST /fetch_cve_data endpoint by manipulating the collection name, projected fields, and regex filter parameters. Attackers can dump the mgmt_users collection to harvest administrative usernames and password hashes for offline cracking. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to a running cve-search instance and the ability to send requests to the POST /fetch_cve_data endpoint; per the CVSS vector (PR:N/UI:N/AC:L/AT:N) no authentication, user interaction, or special preconditions are needed against a default deployment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are consistent and point to a genuine priority for anyone running cve-search. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach a cve-search instance sends a crafted POST to /fetch_cve_data that sets the target collection to mgmt_users and projects the username and password-hash fields, receiving the administrative credential records in the response. They then crack the hashes offline and log in as an administrator. … |
| Remediation | Apply the upstream fix from pull request https://github.com/cve-search/cve-search/pull/1218 by updating to the patched cve-search build (an exact release version is not enumerated in the input, so pull the fixed commit/latest release from the project). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Apply vendor patch for CVE-2026-59509 or take cve-search offline. …
