CVE-2026-73213

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.16.0, addrlesseq in src/client/nsturnioaddr.c uses a component-wise comparison for native IPv6 min-max intervals in ioaaddrinrange, allowing an authenticated TURN client to relay to an IPv6 peer that is numerically...

CVE-2026-73212

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.1, goodpeeraddr in src/server/nsturnserver.c uses ioaaddrinrange in src/client/nsturnioaddr.c without canonicalizing IPv4-compatible, 6to4, and 64:ff9b::/96 NAT64 address forms, allowing an authenticated RFC 6062 T...

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...

CVE-2026-68322

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. A local user can trigger a null pointer dereference by attempting to bind an RDS socket to an IPv6 address when IPv6 is explicitly disabled. This can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-73213 Coturn: `addr_less_eq()` does a component-wise IPv6 comparison instead of a lexicographic one, letting an authenticated TURN client bypass `denied-peer-ip`/`allowed-peer-ip` IPv6 ranges (TURN-specific SSRF)

CVE-2026-73213

CVE-2026-73213 affects the Coturn TURN/STUN server. Prior to 4.16.0, addr_less_eq() used a component-wise IPv6 comparison in ioa_addr_in_range(), allowing an authenticated TURN client to relay to an IPv6 peer that is numerically within a configured denied-peer-ip range but classified as outside i...
