buildSshConnectionArgs interpolated jumpHost raw while its siblings
(identityFile/socksProxy/extraSshOptions) were shellescaped. The token array is
joined and run via execAsync (/bin/sh -c), so a jumpHost like "x; touch /tmp/pwned"
executed. The Zod denylist only blocked backtick/newline/$( and let ;|& and spaces
through.
- shellescape jumpHost in buildSshConnectionArgs (primary fix)
- replace jumpHost denylist with a structural allowlist: [user@]host[:port],
comma-separated multi-hop, bracketed IPv6; no shell metachar can appear
- update/extend tests: escaped -J assertion + injection-safety case
Verified: remote-ssh-options (11) + case-routes (33) pass, tsc --noEmit clean,
regex accepts valid forms / rejects 8 injection payloads.

The Remote case form could only reach port-22, default-identity, directly
SSH-able hosts. Add an escape-hatch set of SSH connection options so Codeman
can reach a host like aa-desktop (custom port 2222, ed25519 identity, cloudflared
SOCKS5 ProxyCommand) the way ssh-aa-desktop does — without shelling out to that
wrapper.
- Model (types/session.ts): new optional RemoteSshOptions (identityFile,
socksProxy, jumpHost, extraSshOptions) on RemoteHost AND SessionRemote; all
absent = today's behavior. toSessionRemote() carries them case->session.
- Shared buildSshConnectionArgs(remote) in remote-hosts.ts: pure, exported,
ordered ssh connection tokens (-o BatchMode=yes, -p, -i <abs identity with
~/$HOME expanded + shellescaped>, -J, -o ProxyCommand=nc -X 5 -x <socks>
%h %p emitted as ONE shellescaped token so %h %p reach ssh literally, then
each extraSshOptions -o). Both buildRemoteLaunchCommand (tmux-manager.ts) and
buildRemoteTmuxCheckCommand now use it, so the prereq probe and the real
launch connect identically. checkRemoteTmuxAvailable widened to accept the
options (callers already pass the full host).
- Validation (schemas.ts): identityFile (no newline/NUL), socksProxy
(host:port), jumpHost (no shell metachars), extraSshOptions (KEY=VALUE,
reject newline/NUL/backtick/$() — defense-in-depth on operator-entered config.
- UI (index.html + session-ui.js): SSH Port field + collapsible "Advanced SSH"
section (identity, SOCKS proxy, jump host, extra -o options one per line);
wired into the remote-host create payload.
Empty-options remotes emit byte-identical ssh to before (pinned by test).
Tests: test/remote-ssh-options.test.ts (buildSshConnectionArgs +
buildRemoteLaunchCommand + buildRemoteTmuxCheckCommand for the aa-desktop set,
escaping/%h %p/identity-~ expansion, byte-identical back-compat); case-routes
schema tests (advanced options round-trip; malformed extraSshOptions/socksProxy
rejected). tsc/eslint/frontend-syntax/prettier/build clean.
Acceptance (real remote, no wrapper): the emitted command connected to
aa-desktop through the cloudflared SOCKS proxy and created a durable remote
tmux session (verified independently via ssh-aa-desktop: CONNECTED_NO_WRAPPER,
STILL_ALIVE_AFTER_DETACH); checkRemoteTmuxAvailable over the proxy returned
{ok:true, tmuxPath:/usr/local/bin/tmux}; test session cleaned up.
