Critical [CVE-2026-73213] Server-Side Request Forgery via incorrect IPv6 comparison
CVE-2026-73213Source published Source updated
Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.16.0, addr_less_eq() in src/client/ns_turn_ioaddr.c uses a component-wise comparison for native IPv6 min-max intervals in ioa_addr_in_range(), allowing an authenticated TURN client to relay to an IPv6 peer that is numerically within a configured non-prefix-aligned denied-peer-ip range but is classified as outside it. This issue is fixed in version 4.16.0. A flaw was found in Coturn. An authenticated TURN client can bypass configured IP address restrictions due to an incorrect component-wise IPv6 comparison in the `addr_less_eq()` function. This allows the client to relay traffic to an IPv6 peer that should be denied, leading to a Server-Side Request Forgery (SSRF) vulnerability. Red Hat products do not ship…
