Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the job name in the 'Keep this build forever' badge tooltip, resulting in a stored cross-site scripting vulnerability.

Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the upstream job's display name shown as part of a build cause, resulting in a stored cross-site scripting vulnerability.

Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the agent name in the build time trend page, resulting in a stored cross-site scripting vulnerability.

Jenkins 2.227 and earlier, LTS 2.204.5 and earlier improperly processes HTML content of list view column headers, resulting in a stored XSS vulnerability exploitable by users able to control column headers.

Jenkins 2.227 and earlier, LTS 2.204.5 and earlier does not set Content-Security-Policy headers for files uploaded as file parameters to a build, resulting in a stored XSS vulnerability.

Jenkins 2.227 and earlier, LTS 2.204.5 and earlier does not properly escape node labels that are shown in the form validation for label expressions on job configuration pages, resulting in a stored XSS vulnerability exploitable by users able to define node labels.

Jenkins 2.227 and earlier, LTS 2.204.5 and earlier uses different representations of request URL paths, which allows attackers to craft URLs that allow bypassing CSRF protection of any target URL.

REST API endpoints in Jenkins 2.218 and earlier, LTS 2.204.1 and earlier were vulnerable to clickjacking attacks.
