CVE-2023-27899

maven/org.jenkins-ci.main/jenkins-core

Incorrect Authorization

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.

All versions after 2.375.4 before 2.394

Upgrade to version 2.394 or above.
