Dabei geht es um eine nicht genauer bekannte Funktion der Datei connaisseur/res/targets_schema.json der Komponente Delegation Name Handler. Durch die Manipulation mit unbekannten Daten kann eine inefficient regular expression complexity-Schwachstelle ausgenutzt werden. Die Komplexit\u00e4t eines Angriffs ist eher hoch. Das Ausnutzen gilt als schwierig. Ein Aktualisieren auf die Version 3.3.1 vermag dieses Problem zu l\u00f6sen. Der Patch wird als 524b73ff7306707f6d3a4d1e86401479bca91b02 bezeichnet.
