CVE-2026-54891

A flaw was found in Erlang's SSL Secure Sockets Layer component. A network-positioned attacker can exploit this vulnerability by injecting unauthenticated plaintext data into a client's TLS Transport Layer Security handshake. The client application may then process this injected data as if it wer...
