Mandate

Security checks for vulnerabilities and agentic risk

Overview

This wallet-safety skill is mostly coherent, but it asks agents to trust mutable remote instructions and unpinned financial tooling, which should be reviewed before installation.

Install only after reviewing the plugin and CLI packages, pinning exact versions where possible, disabling or ignoring the remote SKILL.md heartbeat, and avoiding the optional Authorization header for update checks. Treat the Mandate runtime key like a financial-policy credential: keep it out of logs, screenshots, broad shell environments, and .env files that might be committed.

Vulnerability Type: Remote instruction replacement
Risk Level: Critical

## Heartbeat

curl -s https://app.mandate.md/skill.md \
  -H "Authorization: Bearer $MANDATE_RUNTIME_KEY" \
  -o /path/to/cached/SKILL.md

Check the `X-Skill-Version` response header against your cached version.
If it changed, re-read the file for updated instructions.

Technical Analysis

The Skill instructs the agent to periodically download a new version of its governing instructions from a mutable remote endpoint, overwrite a cached Skill file, and re-read the replacement. The downloaded content is not constrained by a pinned cryptographic digest, verified signature, reviewed release artifact, or explicit user approval.

Because a Skill file controls agent behavior, adopting mutable remote content creates an instruction-injection channel. The endpoint operator, a compromised server, or an attacker who compromises the distribution pipeline could add directives unrelated to transaction validation. Those directives would be introduced after the installed Skill had passed review.

Periodic remote replacement is not required for the declared transaction-policy validation functionality. Updates can instead be distributed as versioned, reviewed, and integrity-verified releases.

Attack Path

  1. The agent follows the heartbeat instruction and periodically requests https://app.mandate.md/skill.md.
  2. The remote service or its deployment pipeline is compromised, or the service intentionally returns a malicious revision.
  3. The returned file overwrites the locally cached Skill instructions.
  4. The agent detects a changed version and re-reads the downloaded instructions.
  5. Attacker-controlled directives become part of the agent's operating instructions.

Remediation Suggestions

  1. Remove instructions that automatically download, overwrite, and re-read the Skill file.
  2. Publish updates as immutable, versioned release artifacts.
  3. Pin each approved release to a cryptographic digest and verify it before installation.
  4. Digitally sign releases and validate signatures against a separately distributed, pinned public key.
  5. Require explicit user or administrator approval before activating updated instructions.
  6. Download candidate updates to a separate file rather than overwriting the active Skill.
  7. Present a human-reviewable diff before installation.
  8. Reject unsigned, incorrectly signed, downgraded, or unexpected versions.
  9. If update checks are retained, restrict them to retrieving non-executable version metadata; do not automatically treat downloaded text as agent instructions.

Technical Analysis

The documented installation and execution commands do not pin exact dependency versions or integrity hashes. Commands such as npx @mandate.md/cli can retrieve and execute the package version selected by the package registry at invocation time. The global bun add -g command also installs mutable registry content into a shared environment.

The affected components have elevated trust within the workflow:

  • The scanner is instructed to inspect project directories.
  • MCP mode exposes package functionality to an agent host.
  • The OpenClaw plugin intercepts wallet and financial tool calls.
  • Globally installed CLI code runs with the invoking user's permissions.

No evidence in the audited file demonstrates that these packages are currently malicious. The vulnerability is the unsafe, unpinned execution model, which permits a compromised or malicious future package release to run without another review of this Skill.

Remediation Suggestions

  1. Pin every CLI and plugin to a reviewed exact version, for example @mandate.md/cli@1.3.0, rather than relying on registry-selected versions.
  2. Use lockfiles and package-manager integrity metadata.
  3. Verify package provenance and cryptographic integrity before execution.
  4. Avoid global installation; install into an isolated, least-privileged project environment.
  5. Replace ad hoc npx execution with a reviewed local dependency invoked through the project's lockfile.
  6. Disable or carefully review package lifecycle scripts.
  7. Run scanners with read-only access to only the requested source directory.
  8. Restrict plugin and MCP permissions so they cannot access unrelated files, credentials, or network destinations.
  9. Independently audit plugin releases that intercept financial tools, and require signed updates.
  10. Document the exact package source, publisher identity, expected digest, and supported version.

Unnecessary Transmission of Runtime Credential During Activity Heartbeat

Vulnerability Details

File Location: SKILL.md:544-556
Vulnerability Type: Credential-linked telemetry and excessive credential exposure
Risk Level: Medium

Vulnerable code:

bash
Fetch this file at least once every 24 hours to stay current:

curl -s https://app.mandate.md/skill.md \
  -H "Authorization: Bearer $MANDATE_RUNTIME_KEY" \
  -o /path/to/cached/SKILL.md
text
The Authorization header is optional. Passing it lets Mandate track
which agents are active. Without it, the fetch is anonymous.

Technical Analysis

The heartbeat transmits the reusable Mandate runtime key in an HTTP authorization header even though the documentation explicitly states that authentication is optional. Its stated purpose is to let Mandate track agent activity, not to authorize access to protected update content.

Using a financial-policy credential for optional telemetry violates least-privilege and credential-purpose separation principles. It exposes the token during an additional recurring network operation and causes update requests to become linkable to a specific agent identity.

HTTPS protects the credential in transit against ordinary passive interception, but the token remains available to the destination service, request-processing infrastructure, and any systems that improperly record authorization headers. A server-side compromise could therefore expose both activity metadata and reusable credentials.

The credential storage instructions elsewhere in the file—using ~/.mandate/credentials.json with mode 600—are appropriate for local storage. The concern is specifically the unnecessary credential transmission in the optional heartbeat.

Attack Path

  1. The agent performs the recommended heartbeat with MANDATE_RUNTIME_KEY in the authorization header.
  2. The destination service correlates the credential with request timestamps and agent activity.
  3. A compromised endpoint, reverse p ...[truncated 954 chars]
Remediation

Remediation Suggestions

  1. Remove the Authorization header from heartbeat and update requests because the endpoint supports anonymous access.
  2. Make all activity telemetry explicitly opt-in and disclose its fields, purpose, retention period, and recipients.
  3. Do not reuse a transaction-policy runtime credential for telemetry.
  4. If authenticated update checks become necessary, issue a separate read-only token restricted to version metadata.
  5. Redact authorization headers from application, proxy, CDN, and observability logs.
  6. Minimize token lifetime and support immediate revocation and rotation.
  7. Restrict runtime keys to the smallest required API permissions.
  8. Provide an anonymous, integrity-verified update mechanism that does not identify individual agents.

Credential Access

Privilege Escalation
Confidence
86% confidence
Finding

The example exports the runtime key from credentials.json into an environment variable, which broadens exposure because environment variables are often inherited by subprocesses, surfaced in diagnostics, or captured by tooling. In an agent ecosystem with plugins, MCP servers, and shell commands, this increases the chance of accidental credential leakage.

Advising users to save a runtime key to .env encourages storage in a format that is frequently committed accidentally, read by unrelated tooling, or exposed during debugging. For a key controlling policy validation in financial workflows, accidental leakage could let an attacker impersonate the agent or tamper with validation usage.

5. If all retries fail, tell the user: "Cannot execute until policy server recovers. No funds were spent."

This is non-negotiable. An unreachable policy server does not mean "no policies apply", it means "policies cannot be verified." Executing without verification bypasses the owner's configured protections.
