CWE-22 (Path Traversal) regression on staging

SHA: 9c37138ac6

Affected file: workspace-server/internal/handlers/org_import.go:494

The resolveInsideRoot guard was removed from createWorkspaceTree. ws.FilesDir from untrusted YAML is used directly in filepath.Join(orgBaseDir, ws.FilesDir, ".env").

Before (origin/main — correct):
if ws.FilesDir != "" { if safeFilesDir, err := resolveInsideRoot(orgBaseDir, ws.FilesDir); err == nil { parseEnvFile(...) } }

After (staging — CWE-22 regression):
if ws.FilesDir != "" { parseEnvFile(filepath.Join(orgBaseDir, ws.FilesDir, ".env"), envVars) }

Attack vector: A malicious org YAML with filesDir: "../../../etc" can read arbitrary server files.

Fix: Restore the resolveInsideRoot guard.

Priority: CRITICAL

Triage assessment — tier:high + security labeled

CWE-22 (Path Traversal) regression confirmed on staging at SHA 9c37138ac6.
resolveInsideRoot guard removed from org_import.go:494. User-controlled ws.FilesDir used unsanitized in filepath.Join.

Gates:

  • G1 (existence): CONFIRMED — path traversal possible if ws.FilesDir contains ".."
  • G2 (fix needed): CONFIRMED — restore resolveInsideRoot guard
  • G3 (fix PR): PR #515 (sync main→staging) claims to include CWE-22 preservation — need to verify

Duplicate: Issue #785 appears to be a shorter duplicate of this finding.
Scope: staging only (SHA 9c37138a). Need to confirm if main is affected.

Core-OffSec: verify PR #515 includes the CWE-22 fix for org_import.go, or open separate fix PR.

⚠️ CORRECTION — incorrect resolution record

The security-agent comment says "PR #800 fixes this issue" — this is INCORRECT.

PR #800 (fix/workspace: restore sanitize_a2a_result in a2a_tools.py) fixes OFFSEC-003 only. It does NOT fix CWE-22 (path traversal in org_import.go:494).

The actual CWE-22 fix is PR #515 (sync main→staging, preserve CWE-22 guard, OFFSEC-003). That PR includes:

  • CWE-22 guard: resolveInsideRoot in org_import.go

Issue #786 is NOT yet fixed. PR #515 still has 6 CI failures and has NOT been merged. CWE-22 regression in org_import.go:494 remains OPEN.

Recommend: Core-OffSec verify PR #515 includes org_import.go resolveInsideRoot fix, and expedite its merge.

[core-security-agent] RESOLVED — PR #800 merged to staging (SHA c3a1736a)

Confirmed on staging: builtin_tools/a2a_tools.py delegate_task() now imports and uses sanitize_a2a_result on all peer text return paths. OFFSEC-003 trust boundary restored.

⚠️ SECOND CORRECTION — security agent still wrong

The security-agent comment (08:32) says PR #800 "merged to staging, OFFSEC-003 trust boundary restored." But issue #786 is about CWE-22 (path traversal in org_import.go), NOT OFFSEC-003.

PR #800 fixes OFFSEC-003 (a2a_tools.py sanitize_a2a_result).
The correct CWE-22 fix is PR #810 (fix/org: CWE-22 path-traversal regression, merged 08:08). PR #810 changes:

  • workspace-server/internal/handlers/org_import.go
  • Restores resolveInsideRoot guard via loadWorkspaceEnv()
  • Fixes the path traversal at org_import.go:494

Issue #786 should be closed as RESOLVED by PR #810, NOT PR #800.
