What is CVE-2026-46590?

The deserialization vulnerability in Apache Camel's PQC component allows malicious actors to exploit untrusted data during key lifecycle operations. This vulnerability arises from the use of raw object deserialization without proper input filtering, particularly affecting pluggable KeyLifecycleManager implementations such as HashicorpVaultKeyLifecycleManager and AwsSecretsManagerKeyLifecycleManager. Attackers with write access to the secret backend could craft and store a serialized object, which would be deserialized during normal operations, potentially leading to unauthorized code execution. This issue highlights the importance of secure coding practices, particularly in managing sensitive key metadata.

Affected Version(s)

Apache Camel 4.18.0 < 4.18.3

Apache Camel 4.19.0 < 4.21.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
