Publication date: 2026-09-05

Last updated on: 2026-09-05

Assigner: VulnCheck

Description
NetBox through 4.7.0 fails to redact sensitive data source backend credentials in REST and GraphQL API responses. Authenticated users with only view permission can retrieve plaintext passwords and secret keys for Git and Amazon S3 backends through API endpoints, gaining unauthorized access to external repositories and storage buckets.

Executive Summary

CVE-2026-86175 is a vulnerability in NetBox versions up to 4.7.0 where authenticated users with view permissions can access sensitive data through REST and GraphQL APIs. This includes plaintext passwords and secret keys for Git and Amazon S3 data source backends, which are normally redacted in the UI but exposed in API responses.

Detection Guidance

Check NetBox API responses for exposed sensitive data. Use curl to query REST API endpoints like /api/dcim/devices/ or /api/extras/data-sources/ with authentication. Inspect GraphQL queries for DataSourceType fields. Compare API output with UI display to identify unredacted credentials or private data.

Impact Analysis

An attacker with view permissions could retrieve credentials for external systems like Git repositories or AWS S3 buckets. This could lead to unauthorized access to sensitive data, lateral movement within networks, or supply-chain attacks by compromising connected systems.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and access controls. It could lead to unauthorized data exposure, breaching GDPR's principle of data confidentiality or HIPAA's safeguards for protected health information.

Mitigation Strategies

Upgrade NetBox to the latest version beyond 4.7.0. Review and restrict API access permissions. Audit all Data Source credentials and rotate exposed passwords or keys. Monitor API logs for unauthorized access attempts.
