What is CVE-2026-86175?

NetBox version 4.7.0 exposes sensitive backend credentials, including Git and Amazon S3 plaintext passwords, through REST and GraphQL API responses. This vulnerability enables authenticated users with view-only permissions to access sensitive credentials, potentially leading to unauthorized access to external repositories and storage buckets. This oversight highlights the importance of implementing strict data redaction practices in APIs to protect sensitive information from being exposed.

Affected Version(s)

netbox 0 <= 4.7.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
