SSH-Weak-DH
About This tool creates SSH connections to a server and goes through different client configurations to check if the server permits a Diffie-Hellman DH key exchange using a weak group. We aim for our tool to help assess SSH servers for weak DH key exchange settings. Please be aware that this tool...
camel-pqc-tls
Post-Quantum TLS with Apache Camel This repository contains three examples demonstrating Post-Quantum Cryptography PQC TLS 1.3 handshakes with Apache Camel, using the X25519MLKEM768 hybrid key exchange. X25519MLKEM768 combines classical X25519 elliptic curve Diffie-Hellman with ML-KEM-768 , a...

GHSA-W3JG-PJXF-73P4 Russh: Missing X25519 zero-point validation in hybrid ML-KEM key exchange
Vulnerability The hybrid ML-KEM 768 + X25519 key exchange implementation in russh/src/kex/hybridmlkem.rs does not validate that the remote peer's X25519 public key is not the zero point all-zero 32-byte value. This allows a remote peer to force the X25519 contribution to the combined shared secre...

CVE-2026-102824
A flaw was found in russh. The library fails to validate peer public keys during hybrid cryptographic key exchange, accepting an all-zero key. A remote attacker acting as a malicious Secure Shell SSH peer can exploit this flaw during connection negotiation to force the classical encryption...
CVE-2026-102824 Russh: Missing X25519 zero-point validation in hybrid ML-KEM key exchange
Russh is a Rust SSH client and server library. Prior to 0.63.0, the hybrid ML-KEM 768 and X25519 implementation in russh/src/kex/hybridmlkem.rs accepts an all-zero 32-byte peer X25519 public key in both serverdh and computesharedsecret, forcing the X25519 contribution to the combined shared secre...
CVE-2026-102824
The Russh Rust SSH client and server library (prior to version 0.63.0 ) contains a vulnerability in the hybrid ML-KEM 768 and X25519 key exchange implementation. The root cause is a missing zero-point validation in russh/src/kex/hybrid_mlkem.rs, which allows the library to accept an all-zero 32-b...
