CVE-2026-62959

A flaw was found in Coturn. When configured with ACME redirect and a plaintext-TCP listener, an unauthenticated remote client can send an HTTP GET request. This action can lead to the disclosure of up to approximately 870 bytes of adjacent process heap memory. On a busy server, this leaked memory...

CVE-2026-65981

A flaw was found in Coturn, an open-source implementation of TURN and STUN servers. An authenticated attacker who obtains a victim's MOBILITY-TICKET can exploit this vulnerability during a session resume. This allows the attacker to take over the victim's TURN Traversal Using Relays around NAT...
