CVE-2026-71469

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).

What the metrics mean

  • It is reachable over a network, without needing local access.
  • For an attacker who can reach it, no special conditions are needed to exploit it.
  • To exploit it, no account is needed.
  • Beyond that, no action by a user is required.
