How to Fix CVE-2026-55478

To remediate this vulnerability, upgrade all affected Snipe/snipe it dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

snipe/snipe-it fixed: 8.6.2 
Upgrade snipe/snipe-it to 8.6.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for snipe/snipe-it

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-55478, inspect your project dependencies for Snipe/snipe it:

inspect dependencies for snipe/snipe-it

Analyze the terminal output to locate any version of Snipe/snipe it in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.6.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Snipe/snipe it, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The API endpoint for adding a license to a predefined kit (`POST /api/v1/kits/{kit_id}/licenses`) only checks whether the caller can edit kits, but does not perform object-level authorization on the referenced license itself. Because of this, a low-privilege user with only predefined-kit permissions can still bind a license that they should not be allowed to access or manage into a kit.
