proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

Impact proxy-addr determines which network hops are trusted proxies so that X-Forwarded-For can be believed. When an application configures a trust subnet as an IPv4-mapped IPv6 address with a short prefix, such as ::ffff:10.0.0.0/8 the correct spelling is ::ffff:10.0.0.0/104, the subnet compiles...

CVE-2026-105689

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, app.util.ssrf/blocked-address? relies on Java InetAddress predicates that do not classify NAT64, 6to4, or Teredo addresses and applies additional CIDR checks only to IPv4 values. Exploitation requires routing through a NAT...

CVE-2026-105648 Ghost: Private IP Filtering Bypass via IPv6 Transition Addresses

Ghost is a Node.js content management system. From 6.0.9 until 6.65.0, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network on some network configurations. A...

CVE-2026-98101

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition in the ip6mcsource function allows concurrent packet processing routines to observe inconsistent multicast source filter lists when entries are modified in place. A local user could exploit this flaw by changing...

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...
