CVE-2026-63505
Published:November 11, 2026
Updated:November 14, 2026
Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.223.1, Probo's console GraphQL API is a multi-tenant GRC platform where all data is scoped to an organization. A Finding can reference a Risk via finding.riskId. That reference is stored without validating that the risk belongs to the caller's organization, and the Finding.risk field resolver authorizes the finding (caller's org) instead of the risk, then loads the risk with a tenant scope derived from the risk's own global ID. As a result, an authenticated member of organization A can attach an arbitrary organization B risk GID to a finding they own and then read organization B's Risk (name, description, treatment, category, severity, owner) — with no membership in B. The stored cross-tenant reference also blocks B from deleting its own risk (ON DELETE RESTRICT), a cross-tenant integrity/DoS. This issue has been patched in version 0.223.1.
