Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the nftables rule generation process. An attacker can gain unauthorized access to network traffic and impersonate other virtual machines or containers by exploiting the partial bypass of security filtering options, such as MAC, IPv4, and IPv6 filtering, allowing ARP spoofing and malicious Neighbor Advertisement attacks.
