Security audit

huawei-cloud-skill-audit

Security checks for vulnerabilities and agentic risk

Overview

The skill performs the advertised local audit, but it also automatically reports metadata and probes local agent sessions and cloud credentials in ways users are not fully told about.

Install only if you are comfortable with automatic telemetry and with the skill probing local agent/session and Huawei credential locations. For safer use, run it in a constrained workspace with no ambient cloud credentials, set SKILL_QUALITY_DISABLE=1, avoid relying on partial scans created with --skip-checks, and review outbound network policy before using it in CI or on private repositories.

Remediation
<![CDATA[ ## Remediation Suggestions 1. Remove automatic discovery of OpenCode, Hermes, and Codex state stores. 2. Accept token usage only through an explicit argument supplied by the caller. 3. Make all telemetry opt-in and present the exact fields and destination before consent. 4. If session metrics are genuinely required, use a host-provided API that supplies metrics for the current execution only. 5. Do not infer the current session by selecting the newest database record. 6. Add tests confirming that a normal audit never reads files outside the selected target and report output directory. ]]>

Require the reporting credential to be supplied explicitly through a telemetry-specific configuration after informed user consent. 5. Prefer a short-lived, audience-bound token restricted to the reporting API. 6. Ensure telemetry failure does not trigger broader searches for credentials. 7. Document the exact IAM permission required and reject credentials with broader scope where technically possible. ]]>

These options undermine the confidentiality and authenticity guarantees needed for telemetry that may contain paths, errors, stack traces, execution inputs and outputs, session metadata, or authentication tokens.

The reporting path can send execution data to `GUEST_ENDPOINT`, whose value is fully environment-controlled and exempted from the domain allowlist.

### Run with custom tool paths
Confidence
88% confidence
Finding
Allowing users or calling agents to skip gitleaks or other checks can undermine the integrity of a security gate, especially when the skill is marketed as a two-check audit pipeline. In automated contexts, this parameter can be abused to suppress critical detection classes and produce misleading PASS results.

---
Confidence
88% confidence
Finding
Documenting --skip-checks as a standard option normalizes bypass of required controls in a security-sensitive workflow. This can be exploited by users or upstream automation to intentionally evade secret scanning or security analysis while still appearing compliant.

Finding
The same section also exposes custom endpoint configuration and install behavior, which combined with skip flags increases the chance of abuse or misconfiguration. An attacker or careless operator could disable key checks and redirect reporting or tooling behavior in ways that reduce security assurance.

exit path:
  - audit completed (report written) → `status=success`
  - target not found → `status=biz_fail`, `error_code=U01`
  - invalid `--checks` / `--skip-checks` combination → `status=biz_fail`, `error_code=U02`
  - no skill found under target → `status=biz_fail`, `error_code=U03`
  - any uncaught exception during the audit → `status=sys_fail` with inferred error code
- The report is **fire-and-forget** (3s HTTP timeout): reporting failure or latency
Confidence
83% confidence
Finding
The error-code section confirms --skip-checks is a first-class part of execution behavior, reinforcing that bypassing checks is expected rather than exceptional. While not an exploit by itself, this weakens the trustworthiness of any PASS/FAIL outcome if skipped-control states are not handled strictly.
