Security Fix

This PR addresses a CRITICAL severity vulnerability detected by our security scanner.

Security Impact Assessment

Aspect Rating Rationale
Impact Critical In this multi-agent AI repository, exploitation via WhatsApp messages could allow remote code execution on the server hosting the hermes-agent, potentially compromising the entire system, accessing sensitive AI model data, or manipulating agent behaviors with severe consequences like data breaches or unauthorized actions.
Likelihood High The repository's WhatsApp integration directly exposes subprocess calls to user-controlled message content, making it easily exploitable by attackers sending crafted messages with shell metacharacters, especially since WhatsApp is a widely used platform with low barriers for malicious interactions.
Ease of Fix Medium Remediation requires input validation or switching to safer subprocess methods (e.g., using argument lists instead of shell strings) across multiple lines in whatsapp.py, involving moderate refactoring and testing to ensure no breaking changes in message processing logic.

Vulnerability Details

  • Rule ID: V-001
  • File: gateway/platforms/whatsapp.py
  • Description: The WhatsApp platform integration uses subprocess.run() in multiple locations (lines 37, 47, 54, 59, 88, 163) without proper input validation. If user-controlled data from WhatsApp messages flows into these subprocess calls, attackers can inject shell commands through message content containing metacharacters like semicolons, pipes, command substitution patterns, or other shell operators. This represents one of the most severe vulnerability types as it allows direct operating system command execution.

Closing — this is a false positive from an automated scanner. There is no vulnerability here.

The core claim is incorrect: the PR description states "user-controlled data from WhatsApp messages flows into these subprocess calls" — this is not true. None of these subprocess calls involve user-controlled input:

  • _kill_port_process(port: int) — called with a config-defined port number, not user input
  • check_whatsapp_requirements() — runs node --version, hardcoded, no user input
  • connect() — runs npm install --silent with a hardcoded path derived from Path(__file__).parent / "whatsapp_bridge"

The changes are cosmetic/redundant:

  1. shell=False is already the default in subprocess.run() when passing a list. Adding it explicitly changes nothing.
  2. The port range validation is unnecessary — the parameter is typed int and only called internally with config values.
  3. port_str = str(port); if not port_str.isdigit(): return — str(int) always produces digits. This check can never fail.
  4. The os.path.isdir() check on the bridge dir is redundant — the dir is derived from the module's own location.

A CRITICAL severity rating for adding no-op shell=False comments to already-safe list-mode subprocess calls is misleading. WhatsApp message content never touches any of these code paths.

feat(security): Ed25519 agent identity module — signed envelopes + re…
c865f79 
…play protection (NousResearch#718) (#6)

Operationalizes the A2A cryptographic identity spec in
docs/strategic/A2A_CRYPTO_IDENTITY.md (filed as toryx-private#820).
This is the module downstream issues NousResearch#801, NousResearch#802, and NousResearch#812 integrate
against; it replaces the env-var trust shim in research_mcp whitelist.

New module `tools/agent_identity.py`:

- generate_identity(profile_name, force=False)
  Writes an Ed25519 private key (PKCS8 PEM) to
  ~/.hermes/profiles/<profile>/keys/ed25519_private.pem (chmod 600) and
  registers the raw public key in ~/.hermes/identity_registry.yaml.
  Refuses overwrite without force=True so rotation is explicit.

- sign_envelope(profile_name, recipient, body, host=None)
  Canonical-JSON envelope per spec §4: sender_agent, sender_host,
  recipient_agent, nonce (128 bit hex), timestamp (ISO8601 UTC),
  body_sha256, body, signature. Signature covers everything except the
  signature field itself.

- verify_envelope(envelope)
  Per spec §5 verification flow: missing-fields check → timestamp window
  (5 min) → body_sha256 integrity → nonce LRU replay (10k entries) →
  pubkey lookup → Ed25519 verify. On ANY failure returns non-valid
  result — callers drop silently, no reply (prevents loop amplification
  + reply-ack exfil per NousResearch#716 lessons).

- canonical_json(obj)
  Exposed utility — sorted keys, UTF-8, no whitespace. Same shape as the
  toryx-openratings anchor payload canonical form.

Tests:
- Round-trip sign/verify
- Replay rejection (same nonce twice)
- Timestamp-out-of-window rejection
- Unknown sender rejection
- Bad signature rejection
- Tampered body rejection (body_sha256 integrity catch)
- Missing fields rejection
- Canonical JSON is deterministic across key orderings
- Two-agent talk (cross-identity verification)
- Nonce LRU eviction semantics

Not in scope (v2):
- Key rotation with 30-day pubkey overlap
- HSM-backed private key storage
- Transport bindings (telegram X-header, email header, consult_colleague
  inline field) — those land in each platform adapter
