OpenBao before 2.6.3 / 2.7.0: when OpenBao Agent or Proxy was configured with require_request_header=true, only the proxy handler was wrapped with the X-Vault-Request header check, so the /agent/v1/quit and /proxy/v1/quit endpoints (and the cache-clear endpoint) accepted requests without the header. This bypasses the SSRF protection the setting is meant to provide and allows a denial of service when enable_quit is on (GHSA-8gmq-wv9h-fcwp).
