    A vulnerability has been discovered in libcommons-lang-java, a set of
    Java classes that provide helper methods for standard Java classes.

    CVE-2025-48924

       An uncontrolled recursion vulnerability was discovered in
       ClassUtils.getClass() that could lead to a StackOverflowError on
       very long inputs.

    For Debian 11 bullseye, this problem has been fixed in version
    2.6-9+deb11u1.

    We recommend that you upgrade your libcommons-lang-java packages.
