AI-Generated

Jenkins versions 2.579 and earlier, as well as LTS 2.568.2 and earlier, are vulnerable due to the system log viewer failing to properly escape log record metadata, leading to a stored cross-site scripting (XSS) vulnerability. This flaw can be exploited by attackers who have control over agent processes, potentially allowing them to execute malicious scripts in the context of the affected Jenkins instance. Organizations using these versions of Jenkins should prioritize remediation to mitigate the risk of XSS attacks.
