info:
  name: Jenkins <=2.196 - Cookie Exposure
  author: c-sh0
  severity: medium
  description: Jenkins through 2.196, LTS 2.176.3 and earlier prints the value of the cookie on the /whoAmI/ URL despite it being marked HttpOnly, thus making it possible to steal cookie-based authentication credentials if the URL is exposed or accessed via another cross-site scripting issue.
