CVE-2026-26014 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. Pion DTLS is a Go implementation of Datagram Transport Layer Security. Pion DTLS versions v1.0.0 through v3.0.10 and 3.1.0 use random nonce generation with AES GCM ciphers, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a "forbidden attack". EPSS estimates a 0.62% chance of exploitation in the next 30 days.
