Path Traversal occurrences in Fortify
Jenkins Fortify Plugin 20.2.34 and earlier does not sanitize the appName and appVersion parameters of its Pipeline steps, allowing attackers with Item/Configure permission to write or overwrite .xml files on the Jenkins controller file system with content not controllable by the attacker. (2022-02-15, CVE-2022-25188)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
