Description
The issue is related to a stored cross-site scripting vulnerability. It occurs because the agent name in the build time trend page is not properly escaped. This can lead to malicious scripts being stored and executed. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited. Technical details include the lack of proper escaping of the
agent name in the build time trend page, which can be exploited through the /buildTimeTrend API endpoint, although the exact endpoint is not explicitly mentioned.Recommendations

For Jenkins LTS versions 2.235.1 and earlier, update to version 2.235.2 or later.
