Description
OpenBao before 2.6.3 contains a missing authorization check that allows attackers to stop Agent and Proxy services by omitting the X-Vault-Header. When require_request_header is enabled, attackers can send requests via server-side request forgery to /agent/v1/quit or /proxy/v1/quit to shut down these services.
