CVE-2026-64861

Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. Prior to version 0.222.0, the GraphQL endpoint does not enforce restrictions on alias count, query depth, or query complexity. An attacker can send a single request containing thousands of aliased resolver calls, causing excessive server-side resource consumption and service degradation. This issue has been patched in version 0.222.0.
