Sensitive Data Exposure in Snipe-IT Prior to 8.3

Publication date: 2026-08-19

Last updated on: 2026-08-19

Assigner: GitHub, Inc.

Description
Snipe-IT is an IT asset/license management system. Prior to 8.6.3, a company-scoped user in FMCS floater mode can access users whose company_id is null because broad API queries and bulk web actions do not consistently apply isCurrentUserHasAccess. The /api/v1/users and /api/v1/users/{id}/licenses endpoints can expose personal data and assigned licenses, /users/bulkeditsave can modify out-of-scope profiles, and /users/merge can soft-delete users and transfer assigned assets. This issue is fixed in version 8.6.3.

Executive Summary

This vulnerability in Snipe-IT allows a company-scoped user in FMCS floater mode to access and modify users without a company association (null-company users). Due to inconsistent authorization checks, these users can view personal data, licenses, and perform bulk actions like merging or deleting accounts across tenants.

Detection Guidance

Check Snipe-IT version for exposure. Run API queries like GET /api/v1/users to see if null-company users are returned. Test bulk actions such as /users/bulkeditsave and /users/merge for unauthorized modifications. Verify if company-scoped users can access or modify out-of-scope profiles.

Impact Analysis

An attacker with company-scoped access could steal sensitive data like PII or licenses, modify user profiles, soft-delete accounts, or transfer assets. This could lead to data breaches, unauthorized access, or asset loss within the system.

Compliance Impact

This vulnerability could violate GDPR by exposing personal data without consent and HIPAA by allowing unauthorized access to sensitive health information. It undermines data protection requirements for tenant isolation and access controls.

Mitigation Strategies

Upgrade Snipe-IT to version 8.6.3 or later. Review user permissions to ensure company-scoped users cannot access null-company users. Audit API endpoints /api/v1/users and /api/v1/users/{id}/licenses for unauthorized data exposure. Disable bulk actions if not required.
