What is CVE-2026-6857?

A vulnerability has been identified in the Camel Infinispan product from Red Hat. This flaw involves unsafe deserialization within the ProtoStream remote aggregation repository. A remote attacker, with minimal privileges, could exploit this weakness by sending specially crafted data. Consequently, this could lead to arbitrary code execution, granting the attacker complete control over the compromised system, thereby jeopardizing the system's confidentiality, integrity, and availability.

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.
