What is CVE-2020-2096?

The Jenkins Gitlab Hook Plugin prior to version 1.4.2 contains a reflected Cross-Site Scripting (XSS) vulnerability due to inadequate escaping of project names in the build_now endpoint. An attacker could exploit this flaw to inject and execute arbitrary scripts in the context of the user's session, compromising web application security and allowing for potential data exfiltration or unauthorized operations. It is crucial for administrators to update to the latest version to mitigate this risk.
