Timestamper Plugin 1.11.1 and earlier does not escape or sanitize the HTML formatting used to display the timestamps in console output for builds.

This results in a stored cross-site scripting vulnerability that can be exploited by users with Overall/Administer permission.

Timestamper Plugin 1.11.2 sanitizes the HTML formatting for timestamps and only allows basic, safe HTML formatting.
