validate target_remote at the install API boundary: hostile strings flow into backend daemon URLs across ALL resolve_*_url helpers - #2467
Conversation
An authenticated caller could pass a hostile target_remote (e.g. 'attacker.example.com:9999/x') that flowed unchecked into resolve_rkllama_url and LXC <target_remote>:<name> addressing, enabling SSRF-shaped daemon URL injection or silent mis-routing to unregistered workers via a degenerate stub capability. Add a single boundary check in install_app before any capability resolution or installer construction: target_remote must be None/empty/"local", a registered cluster worker id, or a bare hostname matching ^[A-Za-z0-9._-]+$. Anything else returns HTTP 400 with reason "invalid_target_remote". Docs-Reviewed: agent-coordination.md documents parallel workflow discipline, not API input validation; no doc change needed for this security hardening.

WARNING: Missing type validation for target_remote — body.get("target_remote") can return any JSON type (int, bool, list, etc.). A truthy non-string value (e.g. 123 or true) passes the target_remote and target_remote != "local" gate and crashes _HOSTNAME_RE.match() with TypeError, producing a 500 instead of a clean 400 rejection.
Coerce or validate the type before applying the regex, e.g. if target_remote is not None and not isinstance(target_remote, str): return JSONResponse({...}, status_code=400).

SUGGESTION: Test name and docstring are misleading. test_target_remote_with_port_and_path_rejected and its docstring reference a path separator (/), but the actual input "10.0.0.1:443@attacker.com" contains : and @ — no /. Consider renaming to test_target_remote_with_port_and_at_sign_rejected and updating the docstring to mention the @ character, which is also listed in the PR's rejection criteria.

Reviewed vs card tsk-3rontv contract + Kilo 2 findings. One confirmed and fixed forward (a021edc). Contract: delivered. ONE boundary validation in Sweep verified (fix-the-class): Kilo dispositions:
Measured on the true merge tree (branch+origin/dev): 22 passed (21 existing incl. the 5 new boundary tests + my non-string test). Replay-check: branch is 1 ahead / 10 behind origin/dev, merge-tree clean (rc=0), no semantic overlap with tonight's merges (#2455–#2466 touched decisions/gates/DecisionsApp; this touches store_install only). APPROVED pending green on a021edc. Merge chain: on green, read any new bot output, merge, ancestor+control verify, close tsk-3rontv. |

Cover None and empty local targets.
The docstring states that "local", None, and "" bypass validation. This test sends only "local". Parametrize the request with all three values so JSON null and an empty string remain accepted.

Reject target names with a trailing newline.
When target_remote is not a registered worker, _HOSTNAME_RE.match() accepts edge-host\n. Use fullmatch() and add a regression test.

CARD TITLE (intent, not commit subject): validate target_remote at the install API boundary: hostile strings flow into backend daemon URLs across ALL resolve_*_url helpers
Autonomous build of board card tsk-3rontv.
An authenticated caller could pass a hostile target_remote (e.g.
'attacker.example.com:9999/x') that flowed unchecked into resolve_rkllama_url
and LXC <target_remote>: addressing, enabling SSRF-shaped daemon URL
injection or silent mis-routing to unregistered workers via a degenerate stub
capability.
Add a single boundary check in install_app before any capability resolution
or installer construction: target_remote must be None/empty/"local", a
registered cluster worker id, or a bare hostname matching ^[A-Za-z0-9._-]+$.
Anything else returns HTTP 400 with reason "invalid_target_remote".
Docs-Reviewed: agent-coordination.md documents parallel workflow discipline, not
API input validation; no doc change needed for this security hardening.
