The flaw is located within the Hessian2Input.readObject function in the /serialize/impl/HessianSerializer.java file. An unauthenticated, remote attacker can exploit this vulnerability by sending specially crafted serialized objects to the vulnerable service. Successful exploitation leads to the deserialization of untrusted data, which can facilitate unauthorized code execution or impact the availability of the application. The project maintainers have classified the issue as \u0026quot;not planned,\u0026quot; and no patch is currently available.
