CVE-2026-6857
CWE-502Published: April 22, 2026· Updated: Apr 22, 2026
Official Description
A flaw was found in camel-infinispan. This vulnerability involves unsafe deserialization in the ProtoStream remote aggregation repository. A remote attacker with low privileges could exploit this by sending specially crafted data, leading to arbitrary code execution. This allows the attacker to gain full control over the affected system, impacting its confidentiality, integrity, and availability.
Technical Analysis
CVE-2026-6857 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.5.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
