Dozzle (Docker log viewer) prior to 10.6.15 isAffected by an SSRF guard bypass in internal/notification/dispatcher/webhook.go: isBlockedIP fails to inspect IPv4 addresses embedded in 6to4, NAT64, Teredo, or IPv4-compatible IPv6 addresses, enabling an authenticated user to reach loopback or link-l...

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...
