CVE-2026-55478 Snipe-IT vulnerability
Snipe-IT is an IT asset/license management system. Prior to 8.6.2, POST /api/v1/kits/{kit_id}/licenses checks whether the caller can edit kits but does not authorize access to the referenced license object, allowing a low-privilege user with predefined-kit permissions to bind a license they should not be able to access or manage into a kit. This issue is fixed in version 8.6.2.
Quick answer
Snipe-IT should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
CVE-2026-55478 affects Snipe-IT asset management deployments where kit-license binding checks kit edit permission but not authorization to the referenced license object. Prioritize shared, multi-company, or internet-facing Snipe-IT instances because the issue can alter assets, users, permissions, or expose data depending on the affected endpoint. Upgrade Snipe-IT to 8.6.2 or a later supported release. Restrict predefined-kit license writes and review license visibility until patched.
- Inventory all Snipe-IT production, staging, and internal asset-management deployments, including containers and hosted instances.
- Identify versions before the fixed Snipe-IT release for CVE-2026-55478: 8.6.2.
- Upgrade Snipe-IT to 8.6.2 or a later supported release, then run database migrations and application cache clears required by the deployment method.
- Restrict predefined-kit license writes and review license visibility until patched.
- Review Snipe-IT roles, granular permissions, API tokens, Full Multiple Companies Support settings, and asset-management workflows for excessive privilege.
- Review web, API, audit, and application logs for suspicious endpoint use, unexpected permission changes, cross-company records, deleted users, or modified assets.
- If unauthorized changes are suspected, revoke tokens, rotate affected credentials, restore modified records from audit history or backup, and preserve evidence.
