CVE-2021-21672 is a medium-severity XML External Entity (XXE) vulnerability affecting Jenkins Selenium HTML Report Plugin versions 1.0 and earlier. This flaw allows an authenticated attacker to potentially read local files on the Jenkins server due to the plugin's XML parser not being properly configured.

The low EPSS score and FAUCET Risk Score further indicate a low likelihood of exploitation in the wild.
