CVE-2026-47697

Shelf has cross-organization IDOR: authenticated users could read/attach another workspace's assets, tags, custodians, bookings, QR codes and audit data

Published Jul 21, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
Shelf is a platform for tracking physical assets. Shelf is multi-tenant; data is isolated per organization (workspace). Prior to version 1.20.2, several endpoints accepted entity IDs from request input and `connect`-ed / read / updated them without verifying the IDs belonged to the caller's organization. An authenticated user in Org A who knew or obtained an ID belonging to Org B could act on Org B's data across organization boundaries (a cross-tenant IDOR). A loader-only restriction on personal-workspace bookings was also bypassable via a crafted POST. Version 1.20.2 patches the issue. No known workarounds are available.
