OpenBao vulnerable to denial of service via malicious JSON request processing (CVE-2025-59043)CVE-2025-59043 0 OpenBao versions prior to 2.4.1 are vulnerable to a denial of service attack via maliciously crafted JSON requests. The vulnerability arises because deserialized JSON objects can consume significantly more memory than their serialized form, allowing attackers to bypass size limits and cause out-of-memory crashes. This occurs early in the request handling process before authentication, enabling unauthenticated attackers to exploit it. Additionally, the audit subsystem may consume excessive CPU when processing requests with many strings. The issue is resolved in OpenBao version 2.4.1.
