axios: Axios: Proxy bypass via IPv4-mapped IPv6 address non-normalization

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not properly normalize IPv4-mapped IPv6 addresses. When a NOPROXY setting is configured to block direct access to specific IPv4 addresses, an attacker can bypass this restriction by using the...

netty-handler: netty-handler: IPv6 subnet rule bypass due to incorrect masking operation

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...
