Fixed In Version: Subversion Plugin 2.15.1
Doc Type: If docs needed, set a value
Doc Text:
An incorrect access restriction vulnerability was found in the Subversion Plugin for Jenkins. An agent's ability to learn the name of a file is not restricted when looking up a subversion key file on the controller. This may allow attackers to control agent processes and read arbitrary files on the Jenkins controller file system.

Description Michael Kaplan 2021-11-04 17:40:58 UTC 
Subversion Plugin 2.15.0 and earlier does not restrict the name of a file when looking up a subversion key file on the controller from an agent.

This allows attackers able to control agent processes to read arbitrary files on the Jenkins controller file system
