CVE-2026-55516 — Snipe-IT is an IT asset/license management system

High CVSS 7.7

Snipe-IT is an IT asset/license management system. Prior to 8.6.2, PATCH or PUT /api/v1/maintenances/{maintenance_id} checks access to the current maintenance record and asset but then fills attacker-controlled fields including asset_id without re-authorizing the newly supplied asset, allowing an authorized user to move a maintenance record onto an asset outside their company scope. This issue is fixed in version 8.6.2.

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
