# CVE-2026-76080: Probo: Unauthenticated cross-tenant and hidden-item disclosure via Query.node in the public Trust Center API

Status: published. Published: 2026-11-11. Updated: 2026-11-11.

Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.224.0, the public Trust Center GraphQL API exposes Query.node(id:) with @authentication(required: OPTIONAL) — an unauthenticated internet visitor to any published trust center can call it. Six of its type branches — Organization, Framework, Audit, ThirdParty (subprocessor), TrustCenter, and TrustCenterReference — resolve the object with a tenant scope derived from the client-supplied GID itself (coredata.NewScopeFromObjectID(id)) and load it with a bare Get(scope, id) that performs no comparison to the current trust center's OrganizationID and no showOnTrustCenter/visibility check. (The Document and File branches, by contrast, correctly pass trustCenter.OrganizationID and check visibility). This issue has been patched in version 0.224.0.
