Linux Distros Unpatched Vulnerability : CVE-2026-53450

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.0, coturn rejects loopback peers by default unless allow-loopback-peers is...

CVE-2026-53450

A flaw was found in Coturn, an open-source implementation of TURN and STUN servers. An authenticated TURN client can bypass the default loopback protection mechanism by using an IPv4-mapped IPv6 peer address. This allows the client to expose services that are intended to be accessible only from t...
