Security audit

SentiClaw

Security checks for vulnerabilities and agentic risk

Overview

SentiClaw appears to be a real security middleware package, but it overstates key protections and has flawed or missing enforcement that users should review before relying on it.

Review this carefully before installing as a security control. It may still be useful as a lightweight text filter and audit helper, but do not rely on it as complete agent sandboxing, tool authorization, SSRF protection, spend control, or guaranteed outbound sanitization without additional enforcement at the actual tool and network execution boundaries. Pin the installer version and decide explicitly whether SQLite audit retention and external alerts are acceptable for your data.

For example, when `/tmp` is allowed, all of the following begin with the same string but are not descendants of `/tmp`: ```text /tmp-escape/secret /tmp_evil/data /tmpbackup/file ``` Calling `realpath()` addresses `..` traversal and existing symbolic links, but it does not correct the missing path-component boundary in the subsequent comparison. ### Attack Path 1. The configuration includes `/tmp` in `allowed_dirs`, as it does by default. 2. An attacker selects or causes creation of a sibling path such as `/tmp-escape/secret`. 3. `realpath()` returns `/tmp-escape/secret`. 4. `"/tmp-escape/secret".startswith("/tmp")` evaluates to true. 5. `check_path()` returns `passed=True`. 6. A caller relying on the result performs the file operation outside the intended directory. ### Impact Assessment If the result is used to authorize file tools, an attacker can access paths outside the configured allowlist. ...[truncated 171 chars]

Finding: Private URL validation permits SSRF through omitted address ranges and DNS resolution

LayerResult: if not block_private: return LayerResult(layer="access", passed=True, risk_level=RiskLevel.SAFE) try: host = urlparse(url).hostname or "" except Exception: return LayerResult(layer="access", passed=False, risk_level=RiskLevel.HIGH, block_message=f"Invalid URL: {url}") if _PRIVATE_IP.match(host) or _INTERNAL_HOST.match(host): return LayerResult(layer="access", passed=False, risk_level=RiskLevel.HIGH, block_message=f"Private/internal host blocked: {host}") return LayerResult(layer="access", passed=True, risk_level=RiskLevel.SAFE) ``` ### Technical Analysis The protection compares only the parsed hostname against a limited set of regular expressions. It omits multiple non-public destinations, including: - IPv4 link-local addresses such as `169.254.0.0/16`. - IPv6 unique-local and link-local ranges. - Reserved, unspecified, multicast, and other non-global addresses. - Alternate textual or numeric representations accepted by some network clients. The validator also does not resolve hostnames. A hostname that appears public can resolve to a loopback, link-local, or private address. DNS rebinding can change the answer between validation and connection. Redirect destinations are not covered by this helper either. ### Attack Path Example direct bypass: 1. An attacker supplies `http://169.254.169.254/`. 2. `urlparse ...[truncated 943 chars]

Finding: Empty tool allowlist fails open and permits every tool
Content: View full analysis
LayerResult: if not allowed_tools or tool_name in allowed_tools: return LayerResult(layer="access", passed=True, risk_level=RiskLevel.SAFE) return LayerResult(layer="access", passed=False, risk_level=RiskLevel.MEDIUM, block_message=f"Tool '{tool_name}' not in allowlist.") ``` ### Technical Analysis An allowlist conventionally permits only entries explicitly present in it. Here, the expression `not allowed_tools` changes an absent or empty policy into unrestricted access. This makes configuration mistakes dangerous: operators who omit `allowed_tools`, intentionally start with an empty list, or expect an empty allowlist to deny all receive the opposite behavior. Because this check is itself not integrated into the normal pipeline, the fail-open default compounds the missing enforcement issue. ### Attack Path 1. The operator uses the default configuration or sets `allowed_tools=[]`. 2. The agent proposes a sensitive tool name not explicitly authorized. 3. `not allowed_tools` evaluates to true. 4. `check_tool()` returns `passed=True`. 5. If the caller trusts this result, the sensitive tool proceeds. ### Impact Assessment The flaw can permit any tool available to the host agent. The resulting impact depends on those tools and may include file access, network requests, command execution, or external API actions within the ...[truncated 46 chars]

Rp1

Medium

Category: MCP Rug Pull
Confidence: 95% confidence
Finding: The README instructs users to execute npx clawhub@latest install senticlaw, which fetches and runs the latest remote package version at install time rather than a pinned, reviewed release. That creates a supply-chain risk: if the upstream package is compromised or a malicious update is published, users could execute attacker-controlled code simply by following the documented installation step.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The README promotes persistent SQLite audit logging and immediate threat alerts to external channels, but does not warn that message content, sender identifiers, session IDs, and other sensitive metadata may be stored or transmitted. In a security middleware context, this is especially risky because the tool processes exactly the kinds of sensitive inputs it claims to protect, so operators may unknowingly create a secondary data-exposure path through logs and alerting systems.
Content: No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 80% confidence
Finding: The skill declares no explicit tool scope or permissions despite documenting installation and alerting behaviors that imply shell/package execution and possible networked integrations. Missing scope metadata weakens least-privilege controls and makes it harder for operators to understand or constrain what the skill may invoke at runtime.
Content: No source excerpt is available for this finding.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 93% confidence
Finding: Using npx clawhub@latest install senticlaw pulls a moving target rather than a pinned, verified version. That creates a supply-chain risk where a compromised or breaking upstream release could execute unexpected code during installation.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The logger automatically forwards security event metadata, including session_id and sender_id, to external messaging channels with no consent, minimization, or redaction controls visible in this code. In a security middleware skill, this is more dangerous because audit events may be triggered by sensitive or adversarial inputs, creating a real risk of privacy leakage, cross-tenant disclosure, or accidental exfiltration to misconfigured third-party destinations.
Content: No source excerpt is available for this finding.
