What is CVE-2021-3401?

A vulnerability in Bitcoin Core allows remote attackers to potentially execute arbitrary code by tricking users into launching the bitcoin-qt program with improperly passed arguments. This issue arises from unsafe handling of the '-platformpluginpath' parameter, which can be exploited through browser interactions or .desktop file configurations. Although the discoverer believes that actual exploitation may not be feasible, this highlights a concern regarding user interactions with system components.
