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).
Weaknesses (CWE)
