CVE-2026-76079: Probo privilege escalation to OWNER via createUser

CVE-2026-76079 · Severity: high · CVSS 7.2 · Published 2026-11-11

Probo is a self-hosted governance and risk management platform. An organization administrator could exploit a flaw in the createUser feature to grant themselves full owner privileges—including the ability to delete the organization and configure SSO—that administrators are normally denied. This allows an attacker with admin access to take complete control of the platform.

Technologies: Probo. Vendors: Probo.

Technical details

The createUser mutation did not enforce the owner-only authorization gate when creating a membership with role OWNER, even though the updateMembership mutation correctly enforced it. An ADMIN caller could invoke createUser with role: OWNER and an attacker-controlled email, bypassing the intent to restrict ownership promotions. The fix adds owner-only checks to createUser and consolidates ownership grants into fail-closed IAM policies keyed on the requested target_role.
