Incorrect Authorization in Jenkins Script Security Plugin
A sandbox bypass vulnerability in Jenkins Script Security Plugin 1.67 and earlier related to the handling of default parameter expressions in closures allowed attackers to execute arbitrary code in sandboxed scripts.

Improper Input Validation in Jenkins Script Security Plugin
Sandbox protection in Jenkins Script Security Plugin 1.69 and earlier could be circumvented during the script compilation phase by applying AST transforming annotations to imports or by using them inside of other annotations.

Improper Input Validation in Jenkins Pipeline: Groovy Plugin
Sandbox protection in Jenkins Pipeline: Groovy Plugin 2.78 and earlier can be circumvented through default parameter expressions in CPS-transformed methods.

Subversion Plugin stored XSS vulnerability
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. Subversion Plugin 2.13.1 escapes the affected part of the error message.

Sandbox bypass vulnerability in Script Security Plugin
Sandbox protection in Script Security Plugin 1.70 and earlier can be circumvented through:
- Crafted constructor calls and bodies (due to an incomplete fix of [SECURITY-582](https://www.jenkins.io/security/advisory/2017-08-07/#super-constructor-calls))
- Crafted method calls on objects that implement `GroovyInterceptable`

This allows attackers able to specify and run sandboxed scripts to execute arbitrary code in the context of the Jenkins controller JVM.

Script Security Plugin 1.71 has additional restrictions and sanity checks to ensure that super constructors cannot be constructed without being intercepted by the sandbox. In addition, it also intercepts method calls on objects that implement `GroovyInterceptable` as calls to `GroovyObject#invokeMethod(String, Object)`, which is on the list of dangerous signatures and should not be approved for use in the sandbox.

Improper Neutralization of Input During Web Page Generation in Jenkins Git Plugin
Jenkins Git Plugin 4.2.0 and earlier does not escape the error message for the repository URL for Microsoft TFS field form validation, resulting in a stored cross-site scripting vulnerability.
