CVE-2026-68930

Russh is a Rust SSH library. Prior to version 0.62.5, it dispatched 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. This could allow callbacks to be reached w...
