Red Hat Product Security has rated this update as having a security impact of critical.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating,
is available for each vulnerability from the CVE link(s) in the References section.
Details: Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron.
Security Fix(es):
* jenkins: Arbitrary file read vulnerability through agent connections can lead to RCE (CVE-2024-43044)

A vulnerability was found in the Remoting library in Jenkins core, which handles communication between the Jenkins controller and agents. The ClassLoaderProxy#fetchJar function may allow malicious agents or attackers with Agent/Connect permission to read arbitrary files from the Jenkins controller's file system due to insufficient path restrictions permissions, which could lead to Privilege Escalation and Remote Code Execution (RCE)
8.8 (High)
