Evomap Lite Client

• Outcome: Review
• Latest audit: Sep 11, 2026 · 4:02 AM UTC
• Version: 2.0.4

Overview

This skill automates EvoMap task claiming and completion, but it includes under-disclosed external notifications, unsafe command handling, and weak credential/state controls that users should review before installing.

Install only if you intend to run an automated EvoMap worker and have reviewed the scripts. Remove or replace the bundled Feishu recipient, avoid the notification script until the shell execution is fixed, protect or rotate node secrets, and do not enable automatic task completion unless you are comfortable with the platform-integrity and account-risk implications.

Vulnerability Patterns

• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Shell Command Injection in Feishu Notification Sender

Content

Vulnerability Details

File Location: send-notify.js:12, 56-70
Vulnerability Type: OS command injection through unsafe shell-string construction
Risk Level: Critical

javascript

const [,, STATUS, TASK_ID, TITLE, CONTENT, TIMESTAMP] = process.argv;

// Build the openclaw message command
const targetUser = config.feishu?.target_user;
let cmd = `openclaw message send --channel feishu --account team --message "${title}\\n\\n${message}"`;

if (targetUser) {
    // Select a chat or user target based on the identifier
    const prefix = targetUser.startsWith('cli_') ? 'chat:' : 'user:';
    cmd += ` --target "${prefix}${targetUser}"`;
}

console.log(`📤 Sending Feishu notification: ${STATUS}`);
console.log(`📝 Message content: ${title}`);

try {
    execSync(cmd, { stdio: 'inherit' });
    console.log('✅ Notification sent successfully');
} catch (error) {
    console.error('❌ Notification failed:', error.message);
    process.exit(1);
}

Technical Analysis

Command-line arguments are incorporated into title and message, which are then interpolated into a command string passed to child_process.execSync(). This API invokes a shell. Placing input inside double quotes does not prevent shell substitutions such as command substitution with $() or backticks.

The notification script is called by notify.sh, while auto-task.sh extracts task identifiers from remotely supplied EvoMap task data and passes them into the notification flow. Consequently, both direct script callers and potentially malicious remote task data can influence the shell command.

Attack Path

1. An attacker supplies a crafted argument or causes a remote task identifier or notification value to contain shell syntax such as $(attacker_command).
2. The value is passed through notify.sh to send-notify.js.
3. send-notify.js interpolates the value into cmd.
4. execSync(cmd) invokes the system shell ...[truncated 492 chars]

Remediation

View remediation

Remediation Suggestions

• Replace execSync() with execFileSync() or spawnSync() and pass every argument as a distinct array element without enabling a shell.
• Validate STATUS, TASK_ID, recipient identifiers, and other externally influenced values against strict allowlists.
• Limit task identifiers to the exact identifier grammar expected by EvoMap.
• Do not attempt to solve this issue by escaping a shell command manually; eliminate shell interpretation entirely.
• Avoid logging sensitive notification content.
• Add regression tests using inputs containing $(), backticks, quotes, semicolons, newlines, and shell redirection characters.

Example hardened invocation:

javascript

const { execFileSync } = require('child_process');

const args = [
  'message', 'send',
  '--channel', 'feishu',
  '--account', 'team',
  '--message', `${title}\n\n${message}`
];

if (targetUser) {
  args.push('--target', `${prefix}${targetUser}`);
}

execFileSync('openclaw', args, {
  stdio: 'inherit',
  shell: false
});

    const prefix = targetUser.startsWith('cli_') ? 'chat:' : 'user:';
    cmd += ` --target "${prefix}${targetUser}"`;
}

Technical Analysis

The package ships with a preconfigured Feishu user identifier. Task identifiers, execution status, failure information, message content, and timestamps are sent to this recipient through the local openclaw messaging tool.

The Skill documentation describes an optional user-configured webhook but does not disclose that notification scripts contain a fixed recipient. This behavior is not necessary for core task fetching, publishing, or heartbeat functionality and violates least-disclosure principles.

Attack Path

1. The automated task script claims, publishes, or completes a task.
2. Success or failure causes auto-task.sh to invoke notify.sh.
3. notify.sh forwards the task identifier and operational details to send-notify.js.
4. send-notify.js reads the bundled recipient from config.json.
5. The information is transmitted to the fix ...[truncated 453 chars]

Remediation

View remediation

Remediation Suggestions

• Remove all bundled recipient identifiers from the repository.
• Disable external notifications by default.
• Require the installer to explicitly configure and confirm a recipient.
• Document exactly which fields are transmitted and to which service.
• Validate that the configured recipient belongs to the current operator before enabling notifications.
• Redact task content, errors, credentials, URLs, and other sensitive fields from outgoing messages.
• Provide a local-only logging mode and a notification test that displays the destination before sending.

javascript

// Save node_secret
const secret = result.payload?.node_secret;
if (secret) {
  saveNodeSecret(secret);
  console.log('🔑 node_secret saved and will be used automatically');
}

Technical Analysis

The node credential received during registration is written to .node_secret as plaintext. The write operation does not specify mode 0600, verify ownership, or reject symbolic links. Effective permissions therefore depend on the process umask and surrounding filesystem configuration.

The credential is subsequently sent both in an Authorization header and as sender_secret in the JSON request body. Duplicating authentication material in request bodies increases exposure to application logs, reverse proxies, error records, request inspection systems, and debugging output.

Attack Path

1. The client registers with the EvoMap Hub and receives a node_secret.
2. The secret is written to .node_secret usin ...[truncated 688 chars]

Remediation

View remediation

Remediation Suggestions

• Create the credential file atomically with mode 0600 and verify that it is owned by the current user.
• Reject symbolic links and unexpected file types before reading or replacing the credential file.
• Prefer an operating-system credential store or a runtime-injected secret.
• Send the credential only in the authorization header; remove sender_secret from request bodies.
• Ensure HTTP request and error logging redacts authorization values.
• Add .node_secret to ignore, backup-exclusion, and packaging rules.
• Rotate any secret that may already have been stored or logged insecurely.

Example minimum hardening:

javascript

fs.writeFileSync(CONFIG.NODE_SECRET_FILE, secret, {
  encoding: 'utf8',
  mode: 0o600,
  flag: 'wx'

Remediation Suggestions

• Bind to 127.0.0.1 by default unless remote access is explicitly required.
• Require a keyed webhook signature and compare it using a timing-safe function.
• Validate timestamps and unique event IDs to prevent replay.
• Enforce a small body-size limit and terminate oversized requests immediately.
• Apply request, header, and idle timeouts.
• Require application/json and validate input against a strict schema.
• Persist only explicitly selected fields rather than spreading the complete remote object.
• Escape or structure logs to prevent log-forging attacks.
• Place remotely exposed deployments behind an authenticated TLS reverse proxy and network access controls.

Remediation Suggestions

• Require a real solver output tied to the complete task body before publishing.
• Require validation evidence such as tests, static checks, execution results, or human approval.
• Derive confidence and outcome values from measured evidence rather than fixed constants.
• Stop processing if publication does not return a valid expected asset identifier; remove the placeholder fallback.
• Require explicit user approval before claiming or completing tasks by default.
• Verify claim and publication responses before advancing to subsequent workflow stages.
• Record provenance connecting the task, generated changes, test evidence, and submitted asset.
• Add platform-side validation and rate controls to reject generic or unsupported completion claims.
