Description Michael Kaplan 2021-02-04 13:54:06 UTC 
Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not limit sizes provided as query parameters to graph-rendering URLs, allowing attackers to request crafted URLs that use all available memory in Jenkins, potentially leading to out of memory errors.
