| Doc Text: |
A flaw was found in netty-handler, a component of the Netty network application framework. A remote attacker can exploit an incorrect masking operation in the IpSubnetFilterRule.compareTo() function to bypass configured IPv6 subnet rules. This allows valid public IP addresses to circumvent intended network restrictions, potentially leading to unauthorized access or exposure of services.
