What is CVE-2025-29953?

The vulnerability in Apache ActiveMQ NMS OpenWire Client prior to version 2.1.1 enables deserialization of untrusted data from untrusted servers. This flaw allows malicious entities to exploit unbounded deserialization, potentially leading to arbitrary code execution on the client. While version 2.1.0 introduced a mechanism to restrict deserialization through an allow/denylist, this feature is susceptible to bypass. Users are strongly urged to upgrade to version 2.1.1 to mitigate this risk and consider transitioning from .NET binary serialization for future-proofing their applications.
