CVE-2026-47697: CWE-863: Incorrect Authorization in Shelf-nu shelf.nu
CVE-2026-47697 is an authorization vulnerability in shelf.nu, a multi-tenant platform for tracking physical assets. Versions prior to 1.20.2 allow authenticated users to access or modify data belonging to other organizations by exploiting insufficient verification of entity IDs. This cross-tenant IDOR (Insecure Direct Object Reference) flaw also permits bypassing a loader-only restriction on personal-workspace bookings. The issue is patched in version 1.20.2. No known workarounds exist.
AI Analysis
Technical Summary
Shelf.nu versions before 1.20.2 contain an incorrect authorization vulnerability (CWE-863) where several endpoints accept entity IDs from user input and perform operations without verifying that the IDs belong to the caller's organization. This allows an authenticated user in one organization to access or act on data belonging to another organization, violating tenant data isolation. Additionally, a loader-only restriction on personal-workspace bookings can be bypassed via a crafted POST request. The vulnerability is fixed in version 1.20.2.
Potential Impact
An attacker with valid credentials in one organization can access or modify data belonging to other organizations, leading to unauthorized data disclosure (high confidentiality impact) and limited data integrity impact. Availability is not affected. This breaks the multi-tenant data isolation model of shelf.nu.
Mitigation Recommendations
Upgrade shelf.nu to version 1.20.2 or later to apply the official fix. No known workarounds are available. Since this is not a cloud service, remediation depends on applying the patch.
