Jenkins Subversion Plugin 2.15.3 and earlier does not escape the name and description of List Subversion tags (and more) parameters on views displaying parameters, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.
A cross-site request forgery (CSRF) vulnerability in Jenkins Subversion Plugin 2.15.3 and earlier allows attackers to connect to an attacker-specified URL.
Jenkins 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.
Jenkins Subversion Plugin 2.13.0 and earlier does not escape the error message for the Project Repository Base URL field form validation, resulting in a stored cross-site scripting vulnerability.
An improper authorization vulnerability exists in Jenkins Subversion Plugin version 2.10.2 and earlier in SubversionStatus.java and SubversionRepositoryStatus.java that allows an attacker with network access to obtain a list of nodes and users.
Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks.
