## Findings

### [HIGH] AGENT-034: Tool Function Without Input Validation

**Location:** `src/cyberbrain26/product/doctor.py:520`

```python
completed = subprocess.run(
```

A tool function accepts string or Any parameters without performing input validation in the function body. This enables tool misuse where attackers can pass malicious inputs to trigger unauthorized actions.


**Fix:** Add input validation at the start of tool functions. Use isinstance() checks, regex validation, or pydantic Field constraints to ensure inputs are safe before processing.

### [CRITICAL] AGENT-026: LangChain Tool Input Not Sanitized

**Location:** `src/cyberbrain26/model_layer/ollama_client.py:36`

```python
self._http = httpx.Client(
```

A @tool decorated function accepts string parameters that flow directly to dangerous operations (file access, command execution, SQL queries, network requests) without input validation or sanitization. This enables Tool Misuse (ASI-02) where attackers can use the tool to perform unauthorized actions.


**Fix:** Validate all string inputs in tool functions before passing to dangerous operations. Use allowlists, regex validation, or type checking to ensure inputs are safe.

### [CRITICAL] AGENT-026: LangChain Tool Input Not Sanitized

**Location:** `src/cyberbrain26/model_layer/ollama_client.py:46`

```python
self._async_http = httpx.AsyncClient(
```

A @tool decorated function accepts string parameters that flow directly to dangerous operations (file access, command execution, SQL queries, network requests) without input validation or sanitization. This enables Tool Misuse (ASI-02) where attackers can use the tool to perform unauthorized actions.


**Fix:** Validate all string inputs in tool functions before passing to dangerous operations. Use allowlists, regex validation, or type checking to ensure inputs are safe.

### [CRITICAL] AGENT-026: LangChain Tool Input Not Sanitized

**Location:** `src/cyberbrain26/model_layer/llama_cpp_client.py:40`

```python
self._http = httpx.Client(
```

A @tool decorated function accepts string parameters that flow directly to dangerous operations (file access, command execution, SQL queries, network requests) without input validation or sanitization. This enables Tool Misuse (ASI-02) where attackers can use the tool to perform unauthorized actions.


**Fix:** Validate all string inputs in tool functions before passing to dangerous operations. Use allowlists, regex validation, or type checking to ensure inputs are safe.

### [CRITICAL] AGENT-026: LangChain Tool Input Not Sanitized

**Location:** `src/cyberbrain26/model_layer/llama_cpp_client.py:50`

```python
self._async_http = httpx.AsyncClient(
```

A @tool decorated function accepts string parameters that flow directly to dangerous operations (file access, command execution, SQL queries, network requests) without input validation or sanitization. This enables Tool Misuse (ASI-02) where attackers can use the tool to perform unauthorized actions.


**Fix:** Validate all string inputs in tool functions before passing to dangerous operations. Use allowlists, regex validation, or type checking to ensure inputs are safe.

### [HIGH] AGENT-034: Tool Function Without Input Validation

**Location:** `src/cyberbrain26/pilot/diff.py:34`

```python
result = subprocess.run(
```

A tool function accepts string or Any parameters without performing input validation in the function body. This enables tool misuse where attackers can pass malicious inputs to trigger unauthorized actions.


**Fix:** Add input validation at the start of tool functions. Use isinstance() checks, regex validation, or pydantic Field constraints to ensure inputs are safe before processing.

### [HIGH] AGENT-034: Tool Function Without Input Validation

**Location:** `src/cyberbrain26/pilot/workflow.py:142`

```python
inside = subprocess.run(
```

A tool function accepts string or Any parameters without performing input validation in the function body. This enables tool misuse where attackers can pass malicious inputs to trigger unauthorized actions.


**Fix:** Add input validation at the start of tool functions. Use isinstance() checks, regex validation, or pydantic Field constraints to ensure inputs are safe before processing.

### [HIGH] AGENT-034: Tool Function Without Input Validation

**Location:** `src/cyberbrain26/pilot/workflow.py:154`

```python
branch = subprocess.run(
```

A tool function accepts string or Any parameters without performing input validation in the function body. This enables tool misuse where attackers can pass malicious inputs to trigger unauthorized actions.


**Fix:** Add input validation at the start of tool functions. Use isinstance() checks, regex validation, or pydantic Field constraints to ensure inputs are safe before processing.

### [HIGH] AGENT-034: Tool Function Without Input Validation

**Location:** `src/cyberbrain26/pilot/workflow.py:629`

```python
return subprocess.run(
```

A tool function accepts string or Any parameters without performing input validation in the function body. This enables tool misuse where attackers can pass malicious inputs to trigger unauthorized actions.


**Fix:** Add input validation at the start of tool functions. Use isinstance() checks, regex validation, or pydantic Field constraints to ensure inputs are safe before processing.

### [HIGH] AGENT-020: Unencrypted or Unauthenticated Inter-Agent Channel

**Location:** `src/cyberbrain26/control_plane/model_gateway/__init__.py:141`

```python
ollama_provider = ProviderRecord(
```

Multi-agent system communicates over unencrypted channels or without mutual authentication. Agents trust other agents based on network location alone, enabling impersonation and message tampering (ASI-07).


**Fix:** Apply mutual TLS (mTLS) to all inter-agent communication. Cryptographically sign all messages between agents. Never trust agent identity based on network location alone.

### [HIGH] AGENT-020: Unencrypted or Unauthenticated Inter-Agent Channel

**Location:** `src/cyberbrain26/control_plane/model_gateway/__init__.py:168`

```python
llama_cpp_provider = ProviderRecord(
```

Multi-agent system communicates over unencrypted channels or without mutual authentication. Agents trust other agents based on network location alone, enabling impersonation and message tampering (ASI-07).


**Fix:** Apply mutual TLS (mTLS) to all inter-agent communication. Cryptographically sign all messages between agents. Never trust agent identity based on network location alone.
