AI-suggested
Upgrade Probo to version 0.222.0 or later, where the vulnerability is patched by enforcing restrictions on alias count, query depth, and query complexity in the GraphQL endpoint. No other mitigation is required as the fix addresses the root cause.
Description
CVE-2026-64861 is a resource exhaustion vulnerability in the Probo GRC platform prior to version 0.222.0. The GraphQL endpoint does not limit alias count, query depth, or query complexity, allowing attackers to craft requests with thousands of aliased resolver calls. This can cause excessive server resource consumption and degrade service availability. The issue is fixed in version 0.222.0.
