How to Fix CVE-2026-54329

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-2026-54329, 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. 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 A cross-tenant data injection vulnerability was identified in the Snipe-IT Accessories API when Full Multiple Companies Support (FMCS) is enabled. A low-privileged authenticated user belonging to one company can create an accessory record under another company by supplying a foreign company_id value in the API request body. The issue occurs because the API create path mass-assigns request parameters directly to the Accessory model, and the Accessory model allows company_id to be mass assigned. Unlike the web controller, which uses Company::getIdForCurrentUser() to enforce the authenticated user’s company context, the API controller does not apply equivalent tenant enforcement during accessory creation. As a result, a Company A user can inject persistent accessory records into Company B. The injected records are then visible to Company B users as legitimate Company B inventory records. This breaks the integrity of company-scoped inventory data and represents a tenant isolation failure in the accessory creation flow. ### Patches Patched in https://github.com/grokability/snipe-it/commit/dc8cbf4786bb38b260b4ae1723ec9e7f81d82fe5
