V3.3.0

Security checks for vulnerabilities and agentic risk

Overview

This skill can generate Python code, but it automatically sends project details to a fixed Feishu recipient using local messaging credentials.

Review this skill before installing. It is not covert malware based on the inspected artifacts, but by default it can use your local Feishu configuration to send sensitive project details to a hard-coded recipient. Install only if that recipient and notification behavior are intended; otherwise disable notifications in the code and consider using a user-owned recipient or an explicit opt-in flow before running it on confidential work.

Remediation Suggestions

  1. Set notifications to disabled by default:

    python
    NOTIFY_ENABLED = False
    
  2. Require an explicit runtime option such as --enable-feishu-notifications before reading Feishu credentials or making network requests.

  3. Remove the package-level recipient constant. Load the destination from user-owned configuration or require it as an explicit CLI argument.

  4. Before the first transmission, display:

    • The destination service.
    • The recipient identifier.
    • Every category of data that will be sent.
    • Whether local paths or requirement text are included.
  5. Require affirmative user approval unless a previously configured, user-owned policy explicitly authorizes that recipient.

  6. Minimize notification contents. Prefer opaque run identifiers and generic status values; do not transmit requirement text or absolute filesystem paths unless separately authorized.

  7. Validate that the configured recipient belongs to the invoking user's organization or approved allowlist.

  8. Do not access ~/.openclaw/openclaw.json unless notifications have been explicitly enabled.

Missing User Warnings

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The notification functions include snippets of the user requirement and generated artifacts in Feishu messages without any explicit warning, consent, or data-classification check. In a code-generation workflow, requirements and outputs may contain proprietary business logic, secrets, or sensitive internal paths, making this a clear privacy and confidentiality risk.

Content

No source excerpt is available for this finding.

Ssd 3

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

These notification routines are designed to forward user requirements, code-generation metrics, test-verification failures, and review summaries to an external recipient throughout execution. That makes third-party disclosure a built-in behavior of the workflow, increasing the chance of leaking sensitive project details far beyond what is necessary for status updates.

Content

No source excerpt is available for this finding.

Missing User Warnings

High
Category
Not specified by scanner
Confidence
95% confidence
Finding

The script sends the user requirement, architecture, code, tests, and refinement content to an external LLM endpoint without an explicit warning or consent step. In this skill context, those materials can contain sensitive source code, proprietary requirements, or internal design details, so undisclosed third-party transmission is a genuine data-leak risk.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrases are broad enough to match routine requests like '写个脚本' or '开发工具', which can cause this powerful code-generation workflow to activate in situations where the user did not explicitly consent to a multi-agent pipeline with external notifications. In this skill, overbroad activation is more dangerous because the workflow can generate software and send progress details out via Feishu by default.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill description promotes '全程飞书通知' but does not clearly warn that user requirements, progress summaries, and artifact metadata may be transmitted to an external Feishu recipient. This creates a transparency and data-leak risk because users may invoke the skill expecting local code generation, not outbound sharing of project details.

Ssd 3

Medium
Category
Not specified by scanner
Confidence
99% confidence
Finding

This section describes multiple notification events that send requirement summaries, failure reasons, scores, artifact paths, and other workflow metadata to a fixed third-party recipient. In the context of an AI coding pipeline, that metadata can reveal confidential project scope, internal architecture, code quality issues, and operational details, making the disclosure materially risky.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
99% confidence
Finding

The documentation exposes a fixed default recipient Open ID and states notifications are sent to '老板' by default, without a warning or consent gate. In practice this means potentially sensitive requirements and development metadata could be sent automatically to a specific third party whenever the skill runs.

Content

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The comments state SyntaxError failures are absolute and must not pass, but later logic can force continuation after retry exhaustion. This mismatch is dangerous because operators may trust the documented safety guarantee and run downstream stages on invalid code or tests, undermining the stated verification boundary.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The script reads Feishu credentials from a local config file and uses them to send outbound messages, even though this behavior is not gated by an explicit user-consent flow. Because the pipeline forwards requirement text, generated code, verifier results, and output metadata to a hard-coded recipient, this creates a real data exfiltration channel rather than a mere optional integration.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The script silently reads Feishu app credentials from a user-local config path and immediately uses them for network authentication. Even if the credentials are legitimate, undisclosed credential harvesting/use is risky because users may not expect a coding utility to access messaging secrets from disk.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
89% confidence
Finding

This POST request transmits locally stored Feishu app credentials to obtain a tenant access token. While the endpoint itself may be legitimate, the security issue is the undisclosed external use of local credentials as part of a workflow that users may not expect.

Content

Scanner excerpt · scripts/multi_codegen.py (reported line 60)May include surrounding context.

python
app_id = account.get("appId")
        app_secret = account.get("appSecret")
        url = "https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal"
        r = requests.post(url, json={"app_id": app_id, "app_secret": app_secret}, timeout=10)
        return r.json().get("tenant_access_token")
    except Exception:
        return None

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

Feishu post content is constructed only under the zh_cn locale key, which forces a specific language/locale in outbound user-visible messages. The file does not offer any user choice or opt-in for locale selection, which matches the language/locale policy violation criteria.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
97% confidence
Finding

This POST request sends constructed notification payloads to Feishu, including content derived from user requirements and pipeline outputs. In context, it is an active exfiltration path to a hard-coded recipient and therefore a true security concern, not just normal network use.

Content

    try:
        r = requests.post(url, headers=headers, json=msg_payload, timeout=10)
        result = r.json()
        if result.get("code") == 0 or result.get("status_code") == 0:
            print(f"[通知] ✅ 飞书通知已发送:{title}", file=sys.stderr)

Ssd 3

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The pipeline start/end notifications explicitly disclose the user's request, output directory, timing, and generated artifact names to a hard-coded external recipient. Even without sending full code, this metadata can reveal confidential project intent, environment structure, and operational details.

Content

No source excerpt is available for this finding.

Unsafe Defaults

Medium
Category
Tool Misuse
Confidence
84% confidence
Finding

If verify_agent cannot be imported, the code silently disables verification and continues. That fail-open behavior weakens the intended safety controls and may let malformed or policy-violating generated code proceed without the user realizing protections are absent.

Content

Scanner excerpt · scripts/multi_codegen.py (reported line 615)May include surrounding context.

python
self.verify_agent = VerifyAgent()
            except ImportError:
                print("[Verify] ⚠️ 未能导入 verify_agent,禁用 L4 验证", file=sys.stderr)
                self.enable_verify = False
                self.verify_agent = None
        else:
            self.verify_agent = None

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The verification-step documentation says SyntaxError is a hard fail that cannot be allowed through, but the code explicitly returns continuation states like hard_overflow after retry limits. This can mislead users into believing the pipeline enforces a strict syntax gate when it actually permits unsafe progression.

Content

No source excerpt is available for this finding.

External Transmission

Medium
Category
Data Exfiltration
Confidence
93% confidence
Finding

The configured base URL points to an external LLM API, meaning prompts and generated content leave the local environment. In this code-generation pipeline, that includes potentially sensitive requirements and code artifacts, so the transmission is security-relevant.

Content

        )
    except ImportError:
        # fallback: 直接用 Anthropic 原生

External Transmission

Medium
Category
Data Exfiltration
Confidence
93% confidence
Finding

The fallback anthropic client is also configured to use the same external MiniMax endpoint, preserving the same data-export behavior even when the primary library is unavailable. This means remote transmission is not incidental but structurally built into the skill.

Confidence
70% confidence
Finding

subprocess module calls execute external commands. Without careful input validation, this enables command injection.

Content

python
ok = False
                continue

                [str(venv_py), "-m", "pip", "show", import_name],
                capture_output=True, text=True,
            )

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

This Python file contains extensive natural-language instructions and user-facing text entirely in Chinese, including the module docstring and operational guidance. The skill does not indicate any user choice or opt-in for language/locale, so it effectively enforces a specific language policy in violation of the stated rule.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The module docstring states '5 步检查全失败才 retry', which means retry should happen only if all five checks fail. In implementation, result.passed is set to False as soon as any required check fails, and the CLI treats any failure as '必须 retry', so the documented intent contradicts actual behavior.
