CVE-2023-27899
First published: Wed Mar 08 2023(Updated: )
A flaw was found in Jenkins. Jenkins creates a temporary file when a plugin is uploaded from an administrator’s computer. If these permissions are overly permissive, they may allow attackers with access to the Jenkins controller file system to read and write the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.
