The vulnerability allows a remote attacker to modify application behavior.

The vulnerability exists due to improper handling of IPv4-mapped IPv6 addresses in net/netip within multiple methods, e.g. IsPrivate, IsLoopback. The affected methods return false for addresses which would return true in their traditional IPv4 forms, leading to potential bypass of implemented security features.

Mitigation
Install updates from vendor's website.
