| Title | datastax pulsar-jms <=9.0.3 Deserialization of Untrusted Data |
|---|
| Description | DataStax pulsar-jms, a JMS 2.0/3.0 client implementation for Apache Pulsar, deserializes ObjectMessage payloads using java.io.ObjectInputStream without any class filtering or type restrictions. An attacker who can publish messages to a Pulsar topic consumed by a JMS consumer can achieve Remote Code Execution (RCE) on the consumer by sending a crafted serialized Java object containing a known gadget chain. |
