CVE-2026-54887: CWE-1394 Use of Default Cryptographic Key in Erlang OTPCVE-2026-54887 0 CVE-2026-54887 is a medium severity vulnerability in Erlang/OTP's ssl DTLS server implementation. It involves the use of a default cryptographic key during server startup, allowing predictable DTLS cookie computation. This flaw enables an attacker who can observe the plaintext ClientHello message to bypass source address verification within the initial 0 to 15 seconds after server startup. The vulnerability affects OTP versions from 20.0 before 29.0.3, 28.5.0.3, and 27.3.4.14, specifically impacting ssl versions from 8.2 before 11.7.3, 11.6.0.3, and 11.2.12.10. The DTLS cookie is intended as a denial-of-service mitigation, not an authentication mechanism, so this bypass could allow handshake amplification with spoofed source addresses during the startup window.
