    Server-side Template Injection (SSTI)

    org.freemarker:freemarker is a "template engine"; a generic tool to generate text output (anything from HTML to auto generated source code) based on templates.

    Affected versions of this package are vulnerable to Server-side Template Injection (SSTI). By allowing user input into java.security.ProtectionDomain.getClassLoader, templates will get access to the java classloader. This can be further leveraged for file system access and code execution. A low-privileged user is sufficient for exploitation of this vulnerability.

    How to fix Server-side Template Injection (SSTI)?

    Upgrade org.freemarker:freemarker to version 2.3.30 or higher.
