Description
A flaw was found in search-v2-api. An unauthenticated attacker can exploit this by sending requests with unique random bearer tokens. Each unique token creates a permanent entry in the unbounded tokenReviews cache, which is not properly cleared. This can lead to memory exhaustion of the search-api pod, resulting in a Denial of Service (DoS).

Remediation

Vendor Workaround

To mitigate this issue, restrict network access to the `search-v2-api` component within Red Hat Advanced Cluster Management for Kubernetes. Implement network policies to limit incoming connections to only trusted sources that require access to the search API. This will reduce the attack surface for unauthenticated denial-of-service attempts. After applying network policies, ensure that the `search-v2-api` pod is restarted to apply the new network rules effectively.
