OpenClaw security audit flags dangerous exec/env patterns in ClawVault plugin (requesting guidance/hardening)

[mikejacksonS2F]

Summary

OpenClaw security audit --deep flags the ClawVault OpenClaw extension as critical risk due to detected shell-exec patterns and env+network patterns in the installed plugin source/dist.

I know static scanners can produce false positives, so this issue is mainly to request maintainer guidance and safer distribution defaults.

Environment

• OpenClaw: 2026.3.1
• Audit command: openclaw security audit --deep
• Installed plugin path reported by OpenClaw: ~/.openclaw/extensions/clawvault/...

What was flagged (examples)

The audit reports multiple occurrences such as:

• dangerous-exec (child_process usage)
• env-harvesting (environment variable access combined with network send)

Example files from the report include:

• dist/plugin/index.js
• src/plugin/index.ts
• src/runtime/runtime-openclaw.ts
• various command/runtime files under src/ and dist/

Requested guidance

Could you clarify:

1. Which of these patterns are expected/required for normal ClawVault operation?
2. What is the intended threat model for the OpenClaw plugin runtime?
3. Recommended hardening for users (least-privilege config, optional feature flags, etc.)?
4. Best practice for pinned, trusted installs (exact version pinning/signing/checksums)?

Suggested improvements

• Document why shell execution is needed (if needed) and where.
• Separate privileged features behind explicit opt-in config.
• Provide release artifacts/instructions that are easier to verify and pin.
• Add a security section mapping scanner findings to expected behavior.

Happy to provide the full raw audit output privately if useful.

Adding a redacted audit snippet for maintainers.

openclaw security audit --deep on OpenClaw 2026.3.1 reports:

• Summary: 1 critical · 4 warn · 1 info
• Critical class: plugins.code_safety
• Message: Plugin "clawvault" contains dangerous code patterns
• Count: 52 critical issue(s) in 429 scanned file(s)

Detected pattern types include:

• dangerous-exec (child_process shell command execution detected)
• env-harvesting (environment variable access combined with network send)

Example file references from the scan:

• dist/plugin/index.js:61
• src/plugin/index.ts:93
• src/runtime/runtime-openclaw.ts:35
• src/lib/search.ts:151
• src/lib/llm-provider.ts:29
• dist/index.cjs:8125
• dist/cli/index.cjs:7024

Also noted by OpenClaw status/audit context:

• plugin loaded from local extension path (~/.openclaw/extensions/clawvault/...)
• hook install recorded as unpinned (clawvault)

No claim of active compromise here — sharing for triage of scanner compatibility, expected behavior documentation, and hardening/pinning guidance.

Good catch surfacing this. The flagged patterns are real but intentional — here's why they exist and what we're doing about it:

Why these patterns exist

dangerous-exec (child_process): ClawVault shells out to qmd (our search/embedding binary) for indexing and search operations. This is by design — qmd is a local binary that runs on your machine, not a remote service. The exec calls are:

• qmd search <collection> <query> — search the vault
• qmd update <collection> — reindex after writes
• qmd embed <collection> — compute embeddings

env-harvesting: We read CLAWVAULT_PATH to locate the vault, SHELL to detect shell config, and HOME for default paths. No environment variables are transmitted anywhere.

network-access: The OpenClaw plugin communicates with the OpenClaw gateway (localhost) to register as a memory provider. No external network calls.

Hardening in progress

1. Input sanitization on exec calls — we'll add explicit argument validation before shelling out to qmd (no user-controlled strings passed unsanitized to exec)
2. Document the security model — adding a SECURITY.md explaining exactly what ClawVault executes and why
3. Consider dropping shell exec — long-term, we want to call qmd as a library (FFI/WASM) instead of shelling out, which eliminates the exec surface entirely

None of the 52 flagged patterns involve remote code execution, data exfiltration, or arbitrary command injection. The static scanner is doing its job correctly — it just can't distinguish between "shells out to a known local binary" and "runs arbitrary commands."

Thanks for the detailed report. Will tag this when the hardening PR lands.

Maintainer Response

Thanks for filing this — these are fair questions. Here's the breakdown:

1. Expected patterns

Shell execution (child_process): Required. ClawVault shells out to qmd (our local embedding/search binary) for indexing and search operations. It also uses git for vault versioning. These are core features, not optional.

Environment variable access: Required. ClawVault reads CLAWVAULT_PATH, GEMINI_API_KEY, OPENAI_API_KEY (for LLM-based fact extraction), and standard Node.js env vars. No env vars are sent externally without explicit user configuration.

Network access: Only used when LLM-based fact extraction is enabled (optional — requires API key configuration). BM25 and local embedding search work fully offline.

2. Threat model

The OpenClaw plugin runs with the same permissions as the host OpenClaw process. It reads/writes markdown files in the configured vault directory and executes qmd/git binaries. It does NOT:

• Execute arbitrary user-supplied shell commands
• Send vault contents to external services (unless LLM extraction is explicitly configured)
• Access files outside the vault directory (except reading its own config)

3. Recommended hardening

• Pin to an exact version in your OpenClaw config: "clawvault": "2.6.5"
• Set CLAWVAULT_PATH to a dedicated directory (not your home dir)
• Omit GEMINI_API_KEY/OPENAI_API_KEY if you don't want LLM fact extraction (disables the only network-dependent feature)
• Review the plugin source at ~/.openclaw/extensions/clawvault/ before enabling

4. Pinned installs

npm install clawvault@2.6.5 --save-exact — npm publishes integrity checksums (SHA-512) in the lockfile. We don't yet have separate signed release artifacts but that's a good suggestion for a future release.

Next steps

• We'll add a SECURITY.md to the repo documenting the exec/env/network patterns and their purposes.
• We'll investigate separating the LLM extraction into an optional dependency so the base package has zero network access.

The scanner findings are all expected behavior for the described features. No hidden or undocumented exec/env patterns exist.

[G9Pedro]

@mikejacksonS2F Thanks for running the deep audit and sharing the output — this is exactly the kind of feedback we need.

The 52 critical count is inflated because the scanner flags every child_process and process.env usage equally. But some of those are legitimate:

• child_process: We shell out to qmd (local embedding search), git, and clawvault CLI. These are intentional and run locally with user-level permissions. No remote code execution.
• env-harvesting: We read CLAWVAULT_PATH and HOME to locate the vault. We don't transmit env vars anywhere.

That said, the audit surfaces real improvements we should make:

1. Allowlist the binaries we exec — only qmd, git, clawvault, and ollama. Reject anything else.
2. Drop execFileSync where possible — move to async with proper error boundaries.
3. Add a SECURITY.md documenting what the plugin executes and why.
4. Sandbox env access — only read the specific vars we need, not pass-through.

Will ship these as a hardening PR. If you have the full audit output (not just summary), happy to triage each finding individually.

[G9Pedro]

Thanks for the thorough report. These findings are expected and here's the context:

Why shell execution exists

ClawVault shells out to:

1. qmd — the local embedding/search engine (BM25 + semantic). This is being replaced with in-process TypeScript in the upcoming v4.0.0 plugin rewrite (PR feat(plugin): v4.0.0 — in-process hybrid retrieval, cross-encoder rerank, adaptive capture #131), which eliminates this exec path entirely.
2. git — for checkpoint/recover session management (commit-based snapshots). This is by design — git provides atomic, auditable state management.
3. Template initialization — clawvault init may exec package managers for optional deps.

Environment variable access

ClawVault reads env vars for:

• LLM API keys (GEMINI_API_KEY, ANTHROPIC_API_KEY, etc.) — needed for observation compression and semantic features
• OpenClaw integration — reading gateway config for provider passthrough
• These are never exfiltrated. Network calls go only to the configured LLM provider endpoints.

Recommended hardening

1. Pin versions: npm install clawvault@2.6.6 (exact version)
2. Disable features you don't need: clawvault config set qmd.enabled false to skip the qmd exec path
3. Review the OpenClaw plugin config: only enable hooks you actually use
4. v4.0.0 will eliminate the largest exec surface (qmd shell-outs → in-process)

Threat model

ClawVault's trust boundary is the local machine — it assumes the agent runtime (OpenClaw) is trusted. It does not make outbound network requests except to explicitly configured LLM providers. There is no telemetry, no phoning home, no data exfiltration.

We'll add a SECURITY.md to the repo documenting this for future audits. Good suggestion on the scanner mapping.
