    Package        : commons-beanutils
    Version        : 1.9.4-1+deb11u1
    CVE ID         : CVE-2025-48734


    commons-beanutils, utility for manipulating Java beans have an
    improper Access Control vulnerability. A special BeanIntrospector
    class was added in version 1.9.2. This can be used to stop attackers
    from using the declared class property of Java enum objects to get
    access to the classloader. However this protection was not enabled by
    default. PropertyUtilsBean (and consequently BeanUtilsBean) now
    disallows declared class level property access by default.


    For Debian 11 bullseye, this problem has been fixed in version
    1.9.4-1+deb11u1.

    We recommend that you upgrade your commons-beanutils packages.
