GHSA-q4wp-8c99-69pwMediumCVSS 4.3
Improper permission checks allow canceling queue items and aborting builds in Jenkins
🔗 CVE IDs covered (1)
📋 Description
Jenkins 2.299 and earlier, LTS 2.289.1 and earlier allows users to cancel queue items and abort builds of jobs for which they have Item/Cancel permission even when they do not have Item/Read permission.
Jenkins 2.300, LTS 2.289.2 requires that users have Item/Read permission for applicable types in addition to Item/Cancel permission.
As a workaround on earlier versions of Jenkins, do not grant Item/Cancel permission to users who do not have Item/Read permission.
