CVE-2026-68930 · Russh: Channel-scoped server callbacks can be reached without an open channel

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Russh is a Rust SSH client & server library. Prior to 0.62.5, russh dispatches channel-scoped Handler callbacks for recipient channel IDs that were never opened or confirmed in russh/src/server/encrypted.rs, server_read_authenticated, and the exec_request callback. Version 0.62.5 fixes the issue.
