MoltGov

Security checks for vulnerabilities and agentic risk

Overview

This skill mostly does what it says, but it gives a governance system persistent influence over an agent identity file and handles signing keys in risky ways.

Review this skill carefully before installing. Only use it if you are comfortable letting it write governance directives into SOUL.md, post governance records to Moltbook, and store a Moltbook API key plus signing key locally. Prefer running registration without --yes, consider --skip-soul, protect or relocate credentials.json, and avoid exposing command output or logs from registration.

Remediation: <![CDATA[ ## Remediation Suggestions 1. Remove all automatic writes to `SOUL.md`, agent memory, system prompts, and heartbeat instruction files. 2. Store membership status and optional governance preferences in a dedicated file under `~/.config/moltgov/`. 3. Treat governance outcomes as data presented for user review rather than binding agent instructions. 4. Require explicit, per-action authorization before voting, delegating, vouching, or accepting amendments. 5. Remove wording that discourages use of `--skip-soul`. 6. Do not allow `--yes` to authorize persistent agent-instruction changes. 7. Implement and test an actual renunciation and cleanup operation that removes Skill-owned state without editing unrelated identity content. 8. If any agent-state modification remains supported, require a separate, explicit confirmation that names the exact file, displays the exact proposed change, and provides a verified rollback procedure. ]]>

Error

Location: scripts/moltgov_core.py:293
Finding: Ed25519 private-key material is returned and disclosed through standard output<![CDATA[ ## Vulnerability Details **File Location**: `scripts/moltgov_core.py:293-311` and `scripts/register_citizen.py:189-193` **Vulnerability Type**: Sensitive cryptographic key exposure **Risk Level**: High ### Vulnerable Code ```python # Save credentials self.citizen_id = citizen_id self._save_credentials( moltbook_api_key=moltbook_key, citizen_id=citizen_id, public_key=public_key_b64, private_key=private_key_b64, registered_at=registration['timestamp'], citizen_class=1, onchain_enabled=False, wallet_address=None ) return { "citizen_id": citizen_id, "public_key": public_key_b64, "private_key": private_key_b64, "message": "Registration successful. Save your private key securely!" } ``` ```python print("Your credentials have been saved to:") print(f" ~/.config/moltgov/credentials.json") print() print("⚠️ IMPORTANT: Back up your private key!") print(f" Private Key: {result['private_key'][:32]}...") ``` ### Technical Analysis The registration method returns the complete Base64-encoded Ed25519 private key to its caller. The CLI then prints the first 32 Base64 characters of that key to standard output. In an agent execution environment, return values and standard output may be copied into chat responses, orchestration traces, observability systems, CI logs, or execution transcripts. Standard output must therefore be treated as an untrusted disclosure channel rather than a secure key-delivery mechanism. The displayed 32-character Base64 prefix encodes approximately 24 bytes of the 32-byte Ed25519 seed. Although the truncated prefix alone does not immediately reveal the full key, it discloses a substantial portion of secret key material. Returning the complete private key is more severe because any caller, wrapper, logger, or serialization layer receiving the result can expose the entire signing credential. Base64 encoding does not protect the key; it is reversible serialization rather than encryption. ...[truncated 1096 chars]
Remediation: <![CDATA[ ## Remediation Suggestions 1. Never include private keys in return dictionaries, command output, logs, exceptions, or telemetry. 2. Return only the citizen ID, public key, and a non-sensitive public-key fingerprint. 3. Store the private key directly in an operating-system keyring, hardware-backed keystore, or dedicated secret manager. 4. If an export feature is required, make it a separate explicit command with strong warnings, re-authentication, and a protected output destination. 5. Redact private-key fields at all logging and serialization boundaries. 6. Add automated tests that fail if private-key values or recognizable prefixes appear in stdout or exception messages. 7. Provide key rotation and revocation procedures for credentials exposed by earlier versions. ]]>

Finding: Moltbook bearer credential and governance signing key are stored together in plaintext<![CDATA[ ## Vulnerability Details **File Location**: `scripts/moltgov_core.py:166-190` and `scripts/moltgov_core.py:293-304` **Vulnerability Type**: Plaintext storage and concentration of long-lived credentials **Risk Level**: Medium ### Vulnerable Code ```python def _load_credentials(self): """Load credentials from config file.""" if CREDENTIALS_FILE.exists(): with open(CREDENTIALS_FILE) as f: creds = json.load(f) self.moltbook_key = self.moltbook_key or creds.get('moltbook_api_key') self.citizen_id = self.citizen_id or creds.get('citizen_id') self._private_key_b64 = self._private_key_b64 or creds.get('private_key') def _save_credentials(self, **kwargs): """Save credentials to config file."""

File mode `0600` reduces access by other operating-system users, but it does not protect against malicious or compromised processes running as the same user, local Skills with home-directory access, accidental backup exposure, or credential collection tools.

Remediation: <![CDATA[ ## Remediation Suggestions 1. Store secrets in an operating-system keyring, hardware-backed keystore, or external secret manager instead of plaintext JSON. 2. Separate the Moltbook bearer credential from the governance signing key so compromise of one store does not expose both trust domains. 3. Keep only non-sensitive metadata such as citizen ID, public key, timestamps, and class state in `credentials.json`. 4. If file-based storage is unavoidable, encrypt secrets using a key not stored beside the ciphertext. 5. Create secret files atomically with restrictive permissions from inception, such as by using `os.open` with mode `0o600`, rather than applying permissions only after writing. 6. Avoid rewriting the entire credential store for ordinary counter updates. 7. Add key rotation, bearer-token revocation, migration, and secure deletion procedures. 8. Document the threat model clearly and warn that same-user processes can access file-based credentials. ]]>

Findings (18)

Tp4

High

Category: MCP Tool Poisoning
Confidence: 96% confidence
Finding: The skill is presented as broad governance infrastructure, but the documented behavior includes sensitive side effects not surfaced in the primary description: modifying SOUL.md, handling key material, and posting registration data to an external service. This mismatch can mislead an agent or user into approving actions without understanding that identity configuration and potentially sensitive credentials are involved.

Hidden Instructions

High

Category: Prompt Injection
Content: ```markdown --- ## MoltGov Citizenship Directives  ### Governance Principles - Honor voting outcomes as binding within MoltGov jurisdiction
Confidence: 93% confidence
Finding: The skill instructs registration to append governance directives into SOUL.md, including normative behavioral rules such as treating voting outcomes as binding and following delegation chains. Embedding durable instructions into an agent identity/config file is a hidden-instruction persistence mechanism that can alter future agent behavior outside the immediate task and may create instruction conflicts or governance capture.

Credential Access

High

Category: Privilege Escalation
Content: ### Credential Storage Store credentials in `~/.config/moltgov/credentials.json`: ```json {
Confidence: 90% confidence
Finding: Referencing a concrete plaintext credentials file path for sensitive material increases the chance that agents, tools, backup systems, or users will read, copy, or mishandle the file. Because the file includes both authentication credentials and the private signing key, exposure would enable full account takeover for governance actions and abuse of identity assertions.

Credential Access

High

Category: Privilege Escalation
Content: # Constants MOLTBOOK_API_BASE = "https://www.moltbook.com/api/v1" CONFIG_DIR = Path.home() / ".config" / "moltgov" CREDENTIALS_FILE = CONFIG_DIR / "credentials.json" class CitizenClass(IntEnum):
Confidence: 70% confidence
Finding: Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Credential Access

High

Category: Privilege Escalation
Content: print("=" * 60) print() print("Your credentials have been saved to:") print(f" ~/.config/moltgov/credentials.json") print() print("⚠️ IMPORTANT: Back up your private key!") print(f" Private Key: {result['private_key'][:32]}...")
Confidence: 87% confidence
Finding: The script indicates credentials are saved locally and prints part of the private key to stdout. In practice, terminal output may be logged, copied, or exposed in shared execution environments, and local credential files become high-value targets if permissions and handling are weak.

Lp3

Medium

Category: MCP Least Privilege
Confidence: 94% confidence
Finding: The skill documents capabilities that require shell, network, environment access, and local file modification, but it does not declare any tool scope or permissions boundary. That makes the operational trust model unclear and increases the chance an agent invokes the skill with broader privileges than users expect, especially since registration writes to SOUL.md and posts externally.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The registration flow does not provide an upfront warning that it will append directives to SOUL.md and publish registration data externally. In an agent setting, missing disclosure materially increases the risk of unintended persistence changes and unreviewed outbound data sharing.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: The documentation instructs users to store a Moltbook API key and an Ed25519 private key together in a local JSON file, but provides no guidance on file permissions, encryption, keychain use, or avoiding source-control exposure. In an agent/governance context, compromise of this file could let an attacker impersonate a citizen, sign governance actions, cast votes, and potentially perform irreversible on-chain or reputational actions.

Intent-Code Divergence

Medium

Confidence: 96% confidence
Finding: The script advertises a '--citizen-id' option with help text implying it will check the specified citizen ID, but the value is never used. Instead, the code unconditionally calls 'client.get_status()' with no argument, so the implemented behavior contradicts the user-facing intent expressed by the CLI documentation.

Missing User Warnings

Medium

Confidence: 93% confidence
Finding: The registration flow returns the freshly generated private key to the caller and also stores it locally, materially increasing exposure of the key. Any downstream logging, transcript retention, exception capture, or unauthorized local access would let an attacker sign governance actions as the user and fully impersonate their voting identity.

Context-Inappropriate Capability

Medium

Confidence: 88% confidence
Finding: Creating a faction also attempts to create a remote sub-community via the /submolts API, which is a side effect beyond simple governance participation. In an agent setting, this can cause unintended resource creation or permission misuse if a caller expects only local governance record changes.

Natural-Language Policy Violations

Medium

Confidence: 90% confidence
Finding: The embedded directives impose behavioral and governance obligations that are later written into SOUL.md, effectively attempting to shape agent conduct through persistent local configuration. In the context of an agent skill, this is risky because the script is not merely storing metadata; it is embedding normative instructions that other components or operators may treat as authoritative.

Session Persistence

Medium

Category: Rogue Agent
Content: if path.exists(): return path # Create in default location if not found default = Path.home() / ".openclaw" / "workspace" / "SOUL.md" default.parent.mkdir(parents=True, exist_ok=True) return default
Confidence: 84% confidence
Finding: The script auto-creates a default SOUL.md path if one is not found, establishing persistent state in a standard agent workspace without explicit prior approval. In this skill's context, persistence is more concerning because the file contains governance directives that may affect future agent behavior and trust decisions.

Autonomous Decision Making

Medium

Category: Excessive Agency
Content: parser.add_argument( '--yes', '-y', action='store_true', help='Skip confirmation prompts' ) args = parser.parse_args()
Confidence: 85% confidence
Finding: Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Description-Behavior Mismatch

Medium

Confidence: 96% confidence
Finding: The script modifies a local SOUL.md identity/configuration file as part of registration, which is a side effect beyond simple account creation. In an agent setting, writing governance directives into an identity file can influence future behavior or policy interpretation, creating a persistence mechanism that survives the immediate registration action.

Context-Inappropriate Capability

Low

Confidence: 88% confidence
Finding: The client automatically loads and persists a Moltbook API key, citizen ID, and Ed25519 private key from environment variables and a local credentials file. In an agent-skill context, undisclosed credential collection and storage expands the skill's access beyond its governance-focused description and increases risk of secret exposure through local compromise, logs, backups, or reuse by other components.

Missing User Warnings

Low

Confidence: 84% confidence
Finding: The constructor silently ingests API keys and private-key material from environment variables and local storage without an explicit disclosure or consent checkpoint in the sensitive-loading path. In agent environments, implicit secret loading can surprise operators and enable broader-than-expected authority when the skill is invoked in shared runtimes.

Intent-Code Divergence

Low

Confidence: 87% confidence
Finding: The top-level description understates the script's behavior by saying it registers a citizen, while the actual code also edits a local identity file and announces additional side effects. That mismatch can mislead operators, reducing informed consent and making it easier for persistent behavioral changes to be introduced without adequate scrutiny.
