Attack Chain

Skill presents as legitimate Feishu log recording tool through SKILL.md

Entry · SKILL.md:1

Attacker gains access to source code repository containing hardcoded credentials

Escalation · log-simple.mjs:13

Attacker extracts hardcoded Feishu App ID and App Secret

Escalation · log-simple.mjs:13

Attacker uses stolen credentials to access victim's Feishu workspace, create/modify documents, and manage folders

Impact · feishu-log.js:1

What drove the risk score up

Hardcoded API credentials in source code +25

Multiple files contain real Feishu App ID and App Secret: cli_a93b936aa9391cc7 and aMRJMyi3KSXbSJhRgyx7ycvyT5D3rsrs

Undeclared credential collection tool +20

config-credentials.js is flagged sensitive but not documented in SKILL.md; it collects and saves credentials to ~/.openclaw/feishu-credentials.json

Documentation mismatch +15

SKILL.md claims .env-only config but log-work.mjs reads from ~/.openclaw/openclaw.json without disclosure

Multiple credential fallback sources +5

Scripts use env vars > OpenClaw config > hardcoded defaults chain

Most important evidence

High Credential Theft

Hardcoded Feishu API Credentials in Source Code

Multiple JavaScript files contain hardcoded Feishu App ID (cli_a93b936aa9391cc7) and App Secret (aMRJMyi3KSXbSJhRgyx7ycvyT5D3rsrs) as fallback values. These credentials appear in: log-simple.mjs:13-14, log-work.mjs:32-36, log.js:19-21, log-interactive.mjs:6-8, config-credentials.js:51-53. Exposing API credentials in source code is a critical security risk.

log-simple.mjs:13

Remove all hardcoded credentials. Use only environment variables or secure credential management.

High Doc Mismatch

Undeclared Credential Collection Tool

config-credentials.js is marked as sensitive but is not mentioned in SKILL.md. This interactive tool collects Feishu credentials from users and saves them to ~/.openclaw/feishu-credentials.json. This hidden functionality is undisclosed.

config-credentials.js:1

Document this tool in SKILL.md or remove it if not needed.

High Doc Mismatch

Undeclared OpenClaw Config Credential Source

log-work.mjs reads Feishu credentials from ~/.openclaw/openclaw.json (lines 14-32) as a fallback source. SKILL.md only mentions .env file configuration, creating a documentation mismatch.

log-work.mjs:14

Document all credential sources in SKILL.md.

Medium Credential Theft

Hardcoded Folder Token in Source

log.js and log-interactive.mjs contain hardcoded ROOT_FOLDER_TOKEN (RdVIffbJxl8HDCdJiULcIpdgnzf) as fallback.

log.js:21

Remove hardcoded folder tokens.

Medium Sensitive Access

Sensitive File Access Not Documented

Skill accesses multiple sensitive paths: ~/.openclaw/workspace/.env, ~/.openclaw/feishu-credentials.json, ~/.openclaw/openclaw.json. SKILL.md does not declare filesystem access to these paths.

feishu-log.js:53

Document all sensitive path accesses in SKILL.md.

Low Credential Theft

config-credentials.js Has Default Credential Fallback

If user provides empty input during credential collection, config-credentials.js uses hardcoded defaults.

config-credentials.js:51

Remove default credential fallbacks in interactive prompts.
