Vulnerability details
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to improper access control in JdbcMessageStore deserialization handling when deserializing data from INT_MESSAGE.MESSAGE_CONTENT. A remote privileged user can write crafted serialized bytes into INT_MESSAGE.MESSAGE_CONTENT to execute arbitrary code.
The issue occurs when the store is used as a Spring-managed bean, because setBeanClassLoader replaces the deserializing converter while the row mapper continues using a stale reference and the configured allow-list is never consulted.
