CVE-2021-21609 is an incorrect authorization vulnerability in Jenkins 2.274 and earlier and Jenkins LTS 2.263.1 and earlier. Jenkins incorrectly compared requested URLs with its list of always-accessible paths. As a result, plugin-provided URLs using certain always-accessible path prefixes could be treated as readable even when the requester lacked the Overall/Read permission.
