CVSS 3.1
7.0 highCVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2023-27899
High (7.0) in jenkins jenkins. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.375.4, 2.387.1, 2.394.
Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a plugin for installation, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used, potentially resulting in arbitrary code execution.
