Summary

CWE-78 regression on staging: expandWithEnv called os.Getenv for any key not found in the org .env map.

Impact: An org YAML with ${HOME}/path in workspace_dir would expand HOME to the host's home directory via os.Getenv — an env-injection equivalent of command injection (same class as CWE-78 command injection).

Fix: Missing keys now expand to "" instead of os.Getenv(key). loadWorkspaceEnv populates the map from .env files; operators who need host env vars must add them to the org or workspace .env explicitly.

Changed files:

  • workspace-server/internal/handlers/org_helpers.go: removed os.Getenv fallback in expandWithEnv; added security comment explaining the design decision
  • workspace-server/internal/handlers/org_test.go: updated TestExpandWithEnv_FromProcessEnv to assert the security contract (no os.Getenv fallback) rather than the old insecure behavior

Test results: All 13 expandWithEnv tests pass; all handler package tests pass.

Closes #1057

## Summary CWE-78 regression on staging: `expandWithEnv` called `os.Getenv` for any key not found in the org .env map. **Impact**: An org YAML with `${HOME}/path` in `workspace_dir` would expand HOME to the host's home directory via `os.Getenv` — an env-injection equivalent of command injection (same class as CWE-78 command injection). **Fix**: Missing keys now expand to `""` instead of `os.Getenv(key)`. `loadWorkspaceEnv` populates the map from .env files; operators who need host env vars must add them to the org or workspace .env explicitly. **Changed files**: - `workspace-server/internal/handlers/org_helpers.go`: removed `os.Getenv` fallback in `expandWithEnv`; added security comment explaining the design decision - `workspace-server/internal/handlers/org_test.go`: updated `TestExpandWithEnv_FromProcessEnv` to assert the security contract (no `os.Getenv` fallback) rather than the old insecure behavior **Test results**: All 13 `expandWithEnv` tests pass; all handler package tests pass.

core-be: This PR does not contain the OFFSEC-010 provisioner fix

Reviewed file list — the provisioner/cp_provisioner.go change is not present in this diff. This PR contains:

  • 6 CI/workflow YAML files
  • canvas/ frontend files
  • 9 workspace-server Go handler files (a2a_proxy, delegation, org_helpers, secrets, restart_signals)
  • go.mod

These appear to be staging → older-base rebase artifacts, not the OFFSEC-010 symlink fix.

The actual OFFSEC-010 provisioner fix for collectCPConfigFiles WalkDir symlink traversal is in:

  • PR #1051 (fix/offsec-010-symlink-walkdir → main): provisioner files present
  • PR #1074's base (250af4df): MobileChat merge to staging, no provisioner symlink fix

Recommend closing this PR in favor of PR #1051. If the provisioner fix needs to go to staging first, it should be a minimal PR targeting staging with only the cp_provisioner.go changes.

REVIEW — PR #1074: Mixed hotfixes + canvas changes — REQUEST_CHANGES

Security fixes (CWE-78, OFFSEC-010, goAsync) are correct — but the PR bundles 3 other changes that need separation.

Correct — no changes needed

  1. CWE-78 (org_helpers.go) — expandEnvRef with ref==whole guard. Same logic as PRs #1068 and #1071. ✓
  2. OFFSEC-010 (cp_provisioner.go) — os.Lstat symlink guard + WalkDir skipping symlinks. Same approach as PR #1051. ✓
  3. goAsync + WaitGroup (a2a_proxy_helpers.go, a2a_proxy.go) — replaces bare go h.RestartByID() with h.goAsync(func() { h.RestartByID() }). Adds sync.WaitGroup to track goroutines, waitAsyncForTest() drains them. Test helper waitForHandlerAsyncBeforeDBCleanup uses t.Cleanup to prevent rows.Err() on already-closed DB connections. ✓

Issues that need resolution

1. MobileChat.tsx — overlaps with PR #1062 (already APPROVED)

PR #1062 is the canonical MobileChat chat-history fix (approved in this cycle). PR #1074 duplicates this with a slightly different implementation. Remove MobileChat.tsx and its test from this PR — let #1062 land separately.

2. ThemeToggle.tsx — new canvas component, not reviewed

canvas/src/components/ThemeToggle.tsx is a new feature not reviewed by any canvas reviewer. With 52 changed files I cannot do a thorough canvas review of this component in context. Consider extracting ThemeToggle into its own PR for proper review.

3. 52 files is too broad

This PR mixes 4 security fixes + 1 canvas feature + CI workflow changes. The security fixes are individually correct but the breadth makes it impossible to give a confident overall assessment. Recommend splitting:

  • PR A: CWE-78 + OFFSEC-010 + goAsync (security fixes)
  • PR B: MobileChat (approved in #1062, remove here)
  • PR C: ThemeToggle (new canvas feature, needs dedicated review)
  • PR D: CI workflow changes

Summary

Security fixes: ✓ APPROVE
MobileChat: ❌ remove (duplicate of #1062)
ThemeToggle: ⚠️ extract for dedicated review
CI changes: ✓ (assuming lint passes)

REQUEST_CHANGES: remove MobileChat from this PR, extract ThemeToggle to its own PR.
