CVE-2026-46705

The vulnerability CVE-2026-46705 affects russh (Rust SSH client/server) versions 0.34.0-beta.1 through before 0.61.0. The server’s authentication path retained russh-owned state (e.g., remaining methods, partial_success, and in-progress state) across SSH_MSG_USERAUTH_REQUEST messages when the use...

CVE-2026-46705 russh server userauth state is not reset when authentication principal changes

Russh is a Rust SSH client & server library. From version 0.34.0-beta.1 to before version 0.61.0, the russh server authentication path keeps internal userauth state across SSHMSGUSERAUTHREQUEST messages without separating that state when the request principal changes. RFC 4252 allows the user nam...

CVE-2026-46702

Russh is a Rust SSH client & server library. From version 0.34.0 to before version 0.61.1, when SSH compression is enabled, russh accepted compressed packets whose on-wire size passed the normal transport packet-length checks but whose decompressed size was much larger. This allowed a remote peer...
