CVE-2025-46712 Information

Description

Erlang/OTP is a set of libraries for the Erlang programming language. In versions prior to OTP-27.3.4 (for OTP-27) OTP-26.2.5.12 (for OTP-26) and OTP-25.3.2.21 (for OTP-25) Erlang/OTP SSH fails to enforce strict KEX handshake hardening measures by allowing optional messages to be exchanged. This allows a Man-in-the-Middle attacker to inject these messages in a connection during the handshake. This issue has been patched in versions OTP-27.3.4 (for OTP-27) OTP-26.2.5.12 (for OTP-26) and OTP-25.3.2.21 (for OTP-25).
