What is CVE-2026-25747?

A deserialization vulnerability exists in the LevelDB component of Apache Camel, allowing attackers to inject crafted serialized Java objects. This occurs when the DefaultLevelDBSerializer class deserializes data from the LevelDB repository using java.io.ObjectInputStream without proper filtering or restrictions. If an attacker can write to the LevelDB database files, they can execute arbitrary code during the deserialization process, posing a significant security threat to affected applications.

Affected Version(s)

Apache Camel LevelDB 3.0.0 < 4.10.9

Apache Camel LevelDB 4.14.0 < 4.14.5

Apache Camel LevelDB 4.15.0 < 4.18.0

Exploit Proof of Concept (PoC)
