Jenkins · Jenkins Perforce Plugin · CVE-2021-21701
**Name of the Vulnerable Software and Affected Versions**
Jenkins Performance Plugin versions 3.20 and earlier
**Description**
The issue is related to the XML parser not being configured to prevent XML external entity (XXE) attacks. This allows attackers who can control workspace contents to have Jenkins parse a crafted XML report file, potentially leading to the extraction of secrets from the Jenkins controller or server-side request forgery.
**Recommendations**
For Jenkins Performance Plugin versions 3.20 and earlier, as a temporary workaround, consider disabling the XML parser until a patch is available. Restrict access to the workspace contents to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
