Summary
NetBox, a network infrastructure management application, is affected by this flaw. An authenticated user who has permission to add components can bypass view restrictions on devices and virtual machines and create components on devices they should not be able to access, and view details of those out-of-scope devices.
Read the original description
NetBox from 2.9.0 before 4.7.4 contains a broken access control vulnerability in BulkComponentCreateView that allows authenticated users to bypass view permissions on parent devices and virtual machines. Attackers with add-component permission can submit arbitrary device or VM IDs, or _all with filters, to view out-of-scope device details and create components on them.
What to do
Upgrade to a fixed version: 4.7.4.

Questions about CVE-2026-116845
Is CVE-2026-116845 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. CISA's SSVC assessment notes a proof of concept exists. No public exploit code is tracked.Source: cve.now feed data
