Until a fix is available, avoid using these JMS message converters in untrusted environments or apply strict input validation and deserialization controls.
Description
A critical deserialization vulnerability exists in Spring Framework's JMS message converters (MappingJackson2MessageConverter and JacksonJsonMessageConverter) when used in untrusted JMS environments. This flaw allows arbitrary class instantiation via gadget class deserialization, potentially enabling unauthorized actions. The vulnerability affects multiple Spring Framework versions from 5.3.0 through 7.0.7.
