Title
Acm-search-v2-api-rhel9: search-v2-api: unbounded tokenreviews cache allows unauthenticated memory-exhaustion dos
Summary
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).
