High [CVE-2026-73212] Server-Side Request Forgery and Remote Code Execution via IP address canonicalization bypass
CVE-2026-73212Source published Source updated
Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.1, good_peer_addr() in src/server/ns_turn_server.c uses ioa_addr_in_range() in src/client/ns_turn_ioaddr.c without canonicalizing IPv4-compatible, 6to4, and 64:ff9b::/96 NAT64 address forms, allowing an authenticated RFC 6062 TCP CONNECT relay client to bypass an IPv4 denied-peer-ip range when the Coturn host has a useful translation route. This issue is fixed in version 4.13.1. A flaw was found in Coturn. This vulnerability can lead to Server-Side Request Forgery (SSRF) and potentially remote code execution (RCE) within the internal network. Coturn is not shipped in any Red Hat product. Red Hat severity: Important — CVSS 7.7 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:L). Weakness: CWE-1389.
