KDE KAuth before 5.55 allows the passing of parameters with arbitrary types to helpers running as root over DBus via DBusHelperProxy.cpp. Certain types can cause crashes, and trigger the decoding of arbitrary images with dynamically loaded plugins. In other words, KAuth unintentionally causes this plugin code to run as root, which increases the severity of any possible exploitation of a plugin vulnerability.

CVE-2019-7443 KAuth vulnerability
Title: KAuth vulnerability
Summary: KAuth could be made to crash or run programs if it received specially crafted
input.
It was discovered that KAuth incorrectly handled some configuration parameters
with specially crafted arbitrary types. An attacker could possibly use this
issue to cause a denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.
