From e91687325db1112a8648e07ac2fc7ed63408b363 Mon Sep 17 00:00:00 2001 From: core-be Date: Fri, 15 May 2026 16:00:59 -0700 Subject: [PATCH 1/3] [stub] Files API: add /agent-home root key, 501 dispatch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1 of internal#425 RFC (Files API roots — container-internal home + system/agent split). Adds the new /agent-home allowedRoots key plus short-circuit dispatch that returns 501 with the canonical pending- message body across List/Read/Write/Delete verbs. Why a stub: - Lets the canvas FilesTab design its root-selector UI against the final shape (the additional option appears in the dropdown today; the body just says "implementation pending"). - The stub-vs-real transition is server-side only — Phase 2b lands the docker-exec backend without canvas changes. - The 501 short-circuit runs BEFORE the DB lookup, so canvases that speculatively GET /agent-home don't generate workspace-not-found noise in logs. Tests: - TestAgentHomeAllowedRoot pins the allowedRoots membership. - TestAgentHomeStub_AllVerbs_Return501 pins the canonical 501 + message body across all four verbs (table-driven for symmetry). - Both assert the stub short-circuits before the DB / EIC / Docker paths, so adding the real backend doesn't have to fight a stale test that exercised a wrong layer. Existing Files API tests (ListFiles / ReadFile / WriteFile / DeleteFile / EIC dispatch / shells) still pass — diff is additive.

Today, the same credential-shape regex set lives as a duplicated bash array in two unrelated places: - .gitea/workflows/secret-scan.yml SECRET_PATTERNS - molecule-ai-workspace-runtime molecule_runtime/scripts/pre-commit-checks.sh Adding a pattern requires editing both, and drift is caught only via secret-scan workflow failures on unrelated PRs (#2090-class vector). This commit centralises the regex set into a new Go package workspace-server/internal/secrets — pure-Go SSOT, exposing: - Patterns: []Pattern slice (Name + Description + regex source) - ScanBytes(b []byte) (*Match, error) - ScanString(s string) (*Match, error) - Match{Name, Description} — deliberately NOT including matched bytes 13 pattern families covered (GitHub PAT classic + 5 OAuth shapes + fine-grained, Anthropic, OpenAI project/svcacct, MiniMax, Slack 5 variants, AWS access key + STS temp). Phase 2b (docker-exec backend) will import secrets.ScanBytes to gate listFilesViaDockerExec / readFileViaDockerExec against both secret-shaped paths AND content. Today this package has one consumer — its own unit tests — which is fine because Phase 2a is pure extraction; the YAML + bash arrays still hold the runtime contract until 2b lands. Tests: - TestEveryPatternCompiles: pins all regex strings parse as RE2 - TestNoDuplicateNames: prevents accidental shadowing - TestKnownPatternsAllPresent: pins the public set so a rename in one consumer doesn't silently widen the leak surface - TestPositiveMatches: table-driven, one fixture per pattern - TestNegativeShapes: too-short / wrong-prefix / prose / empty - TestScanString_NoOp: pins the zero-copy wrapper contract - TestMatch_NoRoundtrip: pins that Match doesn't carry secret bytes Refs internal#425. --- workspace-server/internal/secrets/patterns.go | 226 ++++++++++++++++++ .../internal/secrets/patterns_test.go | 189 +++++++++++++++ 2 files changed, 415 insertions(+) create mode 100644 workspace-server/internal/secrets/patterns.go create mode 100644 workspace-server/internal/secrets/patterns_test.go diff --git a/workspace-server/internal/secrets/patterns.go b/workspace-server/internal/secrets/patterns.go new file mode 100644 index 000000000..13356af7a --- /dev/null +++ b/workspace-server/internal/secrets/patterns.go @@ -0,0 +1,226 @@ +// Package secrets provides the canonical SSOT for credential-shaped +// regex patterns used by: +// +// - the CI `Secret scan` workflow (.gitea/workflows/secret-scan.yml) +// - the runtime's bundled pre-commit hook +// (molecule-ai-workspace-runtime/molecule_runtime/scripts/pre-commit-checks.sh) +// - the upcoming Phase 2b docker-exec Files API backend, which has +// to refuse to surface files whose path OR content matches a +// credential shape (RFC internal#425, Hongming 2026-05-15) +// +// Before this package, the same regex set lived as duplicate bash +// arrays in two unrelated repos; adding a pattern required editing +// both, and pattern drift was caught only via secret-scan workflow +// failures on PRs that had unrelated changes (#2090-class incident +// vector).

Implements the docker-exec backend for the /agent-home root added by #1247 stub. Replaces the 501 short-circuit for ListFiles + ReadFile; WriteFile + DeleteFile remain 501 (Phase 2b-followup will add them with write/delete-time secret-shape gates). DOES need core-security lens review per the RFC's Phase-2b classification (medium risk, new attack surface). Architecture: * New file: workspace-server/internal/handlers/template_files_docker_exec.go * Reuses withEICTunnel from template_files_eic.go — the EIC SSH dance is the same. * Difference: the remote command is wrapped as sudo -n docker exec molecule-workspace sh -c '' so find/cat run INSIDE the container's overlay filesystem, NOT on the host EC2 (which doesn't see the container overlay). * sudo -n: passwordless sudo on EC2 ubuntu by default; -n means fail-fast (no prompt) if that ever changes. * Wrapper shape pinned by TestBuildDockerExec*WrapperShape so a refactor that drops 'docker exec molecule-workspace' visibly breaks here. Per-runtime path resolution (Hongming Decisions §1, internal#425): - openclaw → /root/.openclaw - claude-code → /home/agent/.claude - hermes → /home/agent (NOT /tmp — Hermes runs HOME=/tmp but its state lives at /home/agent/.hermes/. Path resolver is independent of $HOME per the decision.) Pinned by TestAgentHomePathPrefix_HongmingDecisionsSection1. Security gates (the security-review surface): 1. PATH gate. validateRelPath rejects empty, traversal, absolute paths before resolution. resolveAgentHomePath joins against allowlisted agentHomePathPrefix entries only. 2. PATH-secret gate. secrets.ScanString from Phase 2a runs on each entry's path BEFORE returning. A match means the row is DROPPED from the listing (not replaced with a placeholder row — keeping the row would surface the credential-shape filename itself). Empty-result reads as 'no matching files' to the canvas. 3. CONTENT-secret gate. secrets.ScanBytes from Phase 2a runs on the file's bytes BEFORE returning. A match means the body is replaced with the canonical '' marker. The canvas (Phase 3) renders a placeholder INSTEAD of the textarea so the matched bytes never enter the DOM, clipboard, or inspector. 4. DOCKER-EXEC privilege boundary. sudo -n docker exec runs against a hardcoded container name (molecule-workspace) — no user-controlled container name. The container's user is the runtime's choice; we don't add --user. 5. WRITE + DELETE intentionally still 501 in this PR. Phase 2b- followup will add them with the additional discipline of: - reject write if content scanned-secret - reject delete if path scanned-secret (prevents an agent from deleting its own credentials) Splitting read from write keeps THIS PR's security-review surface manageable. templates.go dispatch updates: - ListFiles: the if isAgentHomeStubRequest(rootPath) 501 short- circuit at the top of the handler is REMOVED. Inside the 'if instanceID != ""' SaaS branch, we now branch between listFilesViaDockerExec (when rootPath == /agent-home) and the existing listFilesViaEIC otherwise. - ReadFile: same shape — top-of-handler 501 short-circuit removed, in-SaaS-branch dispatch added. errors.Is is also extended to catch errFileNotExist (in addition to os.ErrNotExist) so the 404 branch covers both. - WriteFile + DeleteFile: 501 short-circuit REMAINS at the top of those handlers (Phase 2b-followup). Tests (template_files_docker_exec_test.go): - TestAgentHomePathPrefix_HongmingDecisionsSection1 — pins Hongming Decisions §1 map - TestResolveAgentHomePath_RejectsTraversal — ../etc/passwd, etc. - TestResolveAgentHomePath_RejectsUnknownRuntime - TestResolveAgentHomePath_NormalPath — happy-path + case-insens runtime + empty-rel returns base - TestBuildDockerExecFindShell_WrapperShape — wrapper shape pin - TestBuildDockerExecCatShell_WrapperShape - TestSecretShapeDeniedMarker_CanonicalString — pins canvas-side constant alignment - TestPathSecretGate_DropsCredentialShapedRows — gate logic - TestContentSecretGate_ReplacesBytesWithMarker — gate logic - TestErrFileNotExist_IsErrorsIsAware — errors.Is wrapping Plus stub-test update: - TestAgentHomeStub_AllVerbs_Return501 renamed to TestAgentHomeStub_StillStubbedVerbs_Return501 and trimmed to Write + Delete only. The List + Read assertions go away because those verbs no longer return 501 for /agent-home. NOT covered by unit tests: the full SSH + docker-exec roundtrip. That's the staging-tenant smoke (Phase 2b SOP gate per feedback_staging_e2e_merge_gate) — fresh EC2-per-workspace tenant on staging, exercise GET .../files?root=/agent-home, verify the canvas renders the real container-internal state.
