It also warns when small models (`<=300B`) are used without sandboxing and with web/browser tools enabled. For webhook ingress, it warns when `hooks.defaultSessionKey` is unset, when request `sessionKey` overrides are enabled, and when overrides are enabled without `hooks.allowedSessionKeyPrefixes`. It also warns when sandbox Docker settings are configured while sandbox mode is off, when `gateway.nodes.denyCommands` uses ineffective pattern-like/unknown entries, when global `tools.profile="minimal"` is overridden by agent tool profiles, and when installed extension plugin tools may be reachable under permissive tool policy. + +## JSON output + +Use `--json` for CI/policy checks: + +```bash +openclaw security audit --json | jq '.summary' +openclaw security audit --deep --json | jq '.findings[] | select(.severity=="critical") | .checkId' +``` + +If `--fix` and `--json` are combined, output includes both fix actions and final report: + +```bash +openclaw security audit --fix --json | jq '{fix: .fix.ok, summary: .report.summary}' +``` + +## What `--fix` changes + +`--fix` applies safe, deterministic remediations: + +- flips common `groupPolicy="open"` to `groupPolicy="allowlist"` (including account variants in supported channels) +- sets `logging.redactSensitive` from `"off"` to `"tools"` +- tightens permissions for state/config and common sensitive files (`credentials/*.json`, `auth-profiles.json`, `sessions.json`, session `*.jsonl`) + +`--fix` does **not**: + +- rotate tokens/passwords/API keys +- disable tools (`gateway`, `cron`, `exec`, etc.) +- change gateway bind/auth/network exposure choices +- remove or rewrite plugins/skills diff --git a/docs/gateway/security/index.md b/docs/gateway/security/index.md index 9f7639a6f0..9b21b80ba4 100644 --- a/docs/gateway/security/index.md +++ b/docs/gateway/security/index.md @@ -17,18 +17,11 @@ Run this regularly (especially after changing config or exposing network surface openclaw security audit openclaw security audit --deep openclaw security audit --fix +openclaw security audit --json ``` It flags common footguns (Gateway auth exposure, browser control exposure, elevated allowlists, filesystem permissions). -`--fix` applies safe guardrails: - -- Tighten `groupPolicy="open"` to `groupPolicy="allowlist"` (and per-account variants) for common channels. -- Turn `logging.redactSensitive="off"` back to `"tools"`. -- Tighten local perms (`~/.openclaw` → `700`, config file → `600`, plus common state files like `credentials/*.json`, `agents/*/agent/auth-profiles.json`, and `agents/*/sessions/sessions.json`). - -Running an AI agent with shell access on your machine is... _spicy_.
