CVE-2020-2290
Stored XSS vulnerability in Jenkins Active Choices Plugin
Description
Jenkins Active Choices Plugin 2.4 and earlier does not escape `List` and `Map` return values of sandboxed scripts for Reactive Reference Parameters. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission. This issue is caused by an incomplete fix for [SECURITY-470](https://www.jenkins.io/security/advisory/2017-10-23/#persisted-cross-site-scripting-vulnerability-in-active-choices-plugin). Active Choices Plugin 2.5 escapes all legal return values of sandboxed scripts.
