Official Description

Java Deserialisation Vulnerability in Jaspersoft Reports Library leads to Remote Code Execution (RCE), potentially allowing code execution on the affected system

NVD Source

Technical Analysis

CVE-2026-6009 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.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
