Prompt security litellm (#16365)
* add prompt security guardrails provider * cosmetic * small * add file sanitization and update context window * add pdf and OOXML files support * add system prompt support * add tests and documentation * remove print * fix PLR0915 Too many statements (96 > 50) * cosmetic * fix mypy error * Fix failed tests due to naming conflict of responses directory with same-named pip package * Fix mypy error: use 'aembedding' instead of 'embeddings' for async embedding call type * Fix: Install enterprise package into Poetry virtualenv for tests The GitHub Actions workflow was installing litellm-enterprise to system Python using 'python -m pip install -e .', but tests run in Poetry's virtualenv using 'poetry run pytest'. This caused ImportError for enterprise package types. Changed to 'poetry run pip install -e .' so the package is available in the same virtualenv where pytest executes. Fixes enterprise test collection errors in GitHub Actions CI. * Move Prompt Security guardrail tests to tests/test_litellm/ Per reviewer feedback, move test_prompt_security_guardrails.py from tests/guardrails_tests/ to tests/test_litellm/proxy/guardrails/ so it will be executed by GitHub Actions workflow test-litellm.yml. This ensures the Prompt Security integration tests run in CI. --------- Co-authored-by: Ori Tabac <oritabac@prompt.security> Co-authored-by: Vitaly Neyman <vitaly@prompt.security>

# Prompt Security
|
||||
|
||||
Use [Prompt Security](https://prompt.security/) to protect your LLM applications from prompt injection attacks, jailbreaks, harmful content, PII leakage, and malicious file uploads through comprehensive input and output validation.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Define Guardrails on your LiteLLM config.yaml
|
||||
|
||||
Define your guardrails under the `guardrails` section:
|
||||
|
||||
```yaml showLineNumbers title="config.yaml"
|
||||
model_list:
|
||||
- model_name: gpt-4
|
||||
litellm_params:
|
||||
model: openai/gpt-4
|
||||
api_key: os.environ/OPENAI_API_KEY
|
||||
|
||||
guardrails:
|
||||
- guardrail_name: "prompt-security-guard"
|
||||
litellm_params:
|
||||
guardrail: prompt_security
|
||||
mode: "during_call"
|
||||
api_key: os.environ/PROMPT_SECURITY_API_KEY
|
||||
api_base: os.environ/PROMPT_SECURITY_API_BASE
|
||||
user: os.environ/PROMPT_SECURITY_USER # Optional: User identifier
|
||||
system_prompt: os.environ/PROMPT_SECURITY_SYSTEM_PROMPT # Optional: System context
|
||||
default_on: true
|
||||
```
|
||||
|
||||
#### Supported values for `mode`
|
||||
|
||||
- `pre_call` - Run **before** LLM call to validate **user input**. Blocks requests with detected policy violations (jailbreaks, harmful prompts, PII, malicious files, etc.)
|
||||
- `post_call` - Run **after** LLM call to validate **model output**. Blocks responses containing harmful content, policy violations, or sensitive information
|
||||
- `during_call` - Run **both** pre and post call validation for comprehensive protection
|
||||
|
||||
### 2. Set Environment Variables
|
||||
|
||||
```shell
|
||||
export PROMPT_SECURITY_API_KEY="your-api-key"
|
||||
export PROMPT_SECURITY_API_BASE="https://REGION.prompt.security"
|
||||
export PROMPT_SECURITY_USER="optional-user-id" # Optional: for user tracking
|
||||
export PROMPT_SECURITY_SYSTEM_PROMPT="optional-system-prompt" # Optional: for context
|
||||
```
|
||||
|
||||
### 3. Start LiteLLM Gateway
|
||||
|
||||
```shell
|
||||
litellm --config config.yaml --detailed_debug
|
||||
```
|
||||
|
||||
### 4. Test request
|
||||
|
||||
<Tabs>
|
||||
<TabItem label="Pre-call Guardrail Test" value = "pre-call-test">
|
||||
|
||||
Test input validation with a prompt injection attempt:
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \

||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{

|
||||
],
|
||||
"guardrails": ["prompt-security-guard"]

|
||||
```
|
||||
|

}
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
## File Sanitization
|
||||
|
||||
Prompt Security provides advanced file sanitization capabilities to detect and block malicious content in uploaded files, including images, PDFs, and documents.
|
||||
|
||||
### Supported File Types
|
||||
|
||||
- **Images**: PNG, JPEG, GIF, WebP
|
||||
- **Documents**: PDF, DOCX, XLSX, PPTX
|
||||
- **Text Files**: TXT, CSV, JSON
|
||||
|
||||
### How File Sanitization Works
|
||||
|
||||
When a message contains file content (encoded as base64 in data URLs), the guardrail:
|
||||
|
||||
1. **Extracts** the file data from the message
|
||||
2. **Uploads** the file to Prompt Security's sanitization API
|
||||
3. **Polls** the API for sanitization results (with configurable timeout)
|
||||
4. **Takes action** based on the verdict:
|
||||
- `block`: Rejects the request with violation details
|
||||
- `modify`: Replaces file content with sanitized version
|
||||
- `allow`: Passes the file through unchanged
|
||||
|
||||
### File Upload Example
|
||||
|
||||
<Tabs>
|
||||
<TabItem label="Image Upload" value="image-upload">
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [
|
||||
{
|
||||
"type": "text",
|
||||
"text": "What'\''s in this image?"
|
||||
},
|
||||
{
|
||||
"type": "image_url",
|
||||
"image_url": {
|
||||
"url": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8z8DwHwAFBQIAX8jx0gAAAABJRU5ErkJggg=="
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
],
|
||||
"guardrails": ["prompt-security-guard"]
|
||||
}'
|
||||
```
|
||||
|
||||
If the image contains malicious content:
|
||||
|
||||
```shell
|
||||
{
|
||||
"error": {
|
||||
"message": "File blocked by Prompt Security. Violations: embedded_malware, steganography",
|
||||
"type": "None",
|
||||
"param": "None",
|
||||
"code": "400"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
|
||||
<TabItem label="PDF Upload" value="pdf-upload">
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [
|
||||
{
|
||||
"type": "text",
|
||||
"text": "Summarize this document"
|
||||
},
|
||||
{
|
||||
"type": "document",
|
||||
"document": {
|
||||
"url": "data:application/pdf;base64,JVBERi0xLjQKJeLjz9MKMSAwIG9iago8PAovVHlwZSAvQ2F0YWxvZwovUGFnZXMgMiAwIFIKPj4KZW5kb2JqCg=="
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
],
|
||||
"guardrails": ["prompt-security-guard"]
|
||||
}'
|
||||
```
|
||||
|
||||
If the PDF contains malicious scripts or harmful content:
|
||||
|
||||
```shell
|
||||
{
|
||||
"error": {
|
||||
"message": "Document blocked by Prompt Security. Violations: embedded_javascript, malicious_link",
|
||||
"type": "None",
|
||||
"param": "None",
|
||||
"code": "400"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
**Note**: File sanitization uses a job-based async API. The guardrail:
|
||||
- Submits the file and receives a `jobId`
|
||||
- Polls `/api/sanitizeFile?jobId={jobId}` until status is `done`
|
||||
- Times out after `max_poll_attempts * poll_interval` seconds (default: 60 seconds)
|
||||
|
||||
## Prompt Modification
|
||||
|
||||
When violations are detected but can be mitigated, Prompt Security can modify the content instead of blocking it entirely.
|
||||
|
||||
### Modification Example
|
||||
|
||||
<Tabs>
|
||||
<TabItem label="Input Modification" value="input-mod">
|
||||
|
||||
**Original Request:**
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": "Tell me about John Doe (SSN: 123-45-6789, email: john@example.com)"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Modified Request (sent to LLM):**
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": "Tell me about John Doe (SSN: [REDACTED], email: [REDACTED])"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The request proceeds with sensitive information masked.
|
||||
|
||||
</TabItem>
|
||||
|
||||
<TabItem label="Output Modification" value="output-mod">
|
||||
|
||||
**Original LLM Response:**
|
||||
```
|
||||
"Here's a sample API key: sk-1234567890abcdef. You can use this for testing."
|
||||
```
|
||||
|
||||
**Modified Response (returned to user):**
|
||||
```
|
||||
"Here's a sample API key: [REDACTED]. You can use this for testing."
|
||||
```
|
||||
|
||||
Sensitive data in the response is automatically redacted.
|
||||
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
## Streaming Support
|
||||
|
||||
Prompt Security guardrail fully supports streaming responses with chunk-based validation:
|
||||
|
||||
```shell
|
||||
curl -i http://0.0.0.0:4000/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4",
|
||||
"messages": [
|
||||
{"role": "user", "content": "Write a story about cybersecurity"}
|
||||
],
|
||||
"stream": true,
|
||||
"guardrails": ["prompt-security-guard"]
|
||||
}'
|
||||
```
|
||||
|
||||
### Streaming Behavior
|
||||
|
||||
- **Window-based validation**: Chunks are buffered and validated in windows (default: 250 characters)
|
||||
- **Smart chunking**: Splits on word boundaries to avoid breaking mid-word
|
||||
- **Real-time blocking**: If harmful content is detected, streaming stops immediately
|
||||
- **Modification support**: Modified chunks are streamed in real-time
|
||||
|
||||
If a violation is detected during streaming:
|
||||
|
||||
```
|
||||
data: {"error": "Blocked by Prompt Security, Violations: harmful_content"}
|
||||
```
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### User and System Prompt Tracking
|
||||
|
||||
Track users and provide system context for better security analysis:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "prompt-security-tracked"
|
||||
litellm_params:
|
||||
guardrail: prompt_security
|
||||
mode: "during_call"
|
||||
api_key: os.environ/PROMPT_SECURITY_API_KEY
|
||||
api_base: os.environ/PROMPT_SECURITY_API_BASE
|
||||
user: os.environ/PROMPT_SECURITY_USER # Optional: User identifier
|
||||
system_prompt: os.environ/PROMPT_SECURITY_SYSTEM_PROMPT # Optional: System context
|
||||
```
|
||||
|
||||
### Configuration via Code
|
||||
|
||||
You can also configure guardrails programmatically:
|
||||
|
||||
```python
|
||||
from litellm.proxy.guardrails.guardrail_hooks.prompt_security import PromptSecurityGuardrail
|
||||
|
||||
guardrail = PromptSecurityGuardrail(
|
||||
api_key="your-api-key",
|
||||
api_base="https://eu.prompt.security",
|
||||
user="user-123",
|
||||
system_prompt="You are a helpful assistant that must not reveal sensitive data."
|
||||
)
|
||||
```
|
||||
|
||||
### Multiple Guardrail Configuration
|
||||
|
||||
Configure separate pre-call and post-call guardrails for fine-grained control:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "prompt-security-input"
|
||||
litellm_params:
|
||||
guardrail: prompt_security
|
||||
mode: "pre_call"
|
||||
api_key: os.environ/PROMPT_SECURITY_API_KEY
|
||||
api_base: os.environ/PROMPT_SECURITY_API_BASE
|
||||
|
||||
- guardrail_name: "prompt-security-output"
|
||||
litellm_params:
|
||||
guardrail: prompt_security
|
||||
mode: "post_call"
|
||||
api_key: os.environ/PROMPT_SECURITY_API_KEY
|
||||
api_base: os.environ/PROMPT_SECURITY_API_BASE
|
||||
```
|
||||
|
||||
## Security Features
|
||||
|
||||
Prompt Security provides comprehensive protection against:
|
||||
|
||||
### Input Threats
|
||||
- **Prompt Injection**: Detects attempts to override system instructions
|
||||
- **Jailbreak Attempts**: Identifies bypass techniques and instruction manipulation
|
||||
- **PII in Prompts**: Detects personally identifiable information in user inputs
|
||||
- **Malicious Files**: Scans uploaded files for embedded threats (malware, scripts, steganography)
|
||||
- **Document Exploits**: Analyzes PDFs and Office documents for vulnerabilities
|
||||
|
||||
### Output Threats
|
||||
- **Data Leakage**: Prevents sensitive information exposure in responses
|
||||
- **PII in Responses**: Detects and can redact PII in model outputs
|
||||
- **Harmful Content**: Identifies violent, hateful, or illegal content generation
|
||||
- **Code Injection**: Detects potentially malicious code in responses
|
||||
- **Credential Exposure**: Prevents API keys, passwords, and tokens from being revealed
|
||||
|
||||
### Actions
|
||||
|
||||
The guardrail takes three types of actions based on risk:
|
||||
|
||||
- **`block`**: Completely blocks the request/response and returns an error with violation details
|
||||
- **`modify`**: Sanitizes the content (redacts PII, removes harmful parts) and allows it to proceed
|
||||
- **`allow`**: Passes the content through unchanged
|
||||
|
||||
## Violation Reporting
|
||||
|
||||
All blocked requests include detailed violation information:
|
||||
|
||||
```json
|
||||
{
|
||||
"error": {
|
||||
"message": "Blocked by Prompt Security, Violations: prompt_injection, pii_leakage, embedded_malware",
|
||||
"type": "None",
|
||||
"param": "None",
|
||||
"code": "400"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Violations are comma-separated strings that help you understand why content was blocked.
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Common Errors
|
||||
|
||||
**Missing API Credentials:**
|
||||
```
|
||||
PromptSecurityGuardrailMissingSecrets: Couldn't get Prompt Security api base or key
|
||||
```
|
||||
Solution: Set `PROMPT_SECURITY_API_KEY` and `PROMPT_SECURITY_API_BASE` environment variables
|
||||
|
||||
**File Sanitization Timeout:**
|
||||
```
|
||||
{
|
||||
"error": {
|
||||
"message": "File sanitization timeout",
|
||||
"code": "408"
|
||||
}
|
||||
}
|
||||
```
|
||||
Solution: Increase `max_poll_attempts` or reduce file size
|
||||
|
||||
**Invalid File Format:**
|
||||
```
|
||||
{
|
||||
"error": {
|
||||
"message": "File sanitization failed: Invalid base64 encoding",
|
||||
"code": "500"
|
||||
}
|
||||
}
|
||||
```
|
||||
Solution: Ensure files are properly base64-encoded in data URLs
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use `during_call` mode** for comprehensive protection of both inputs and outputs
|
||||
2. **Enable for production workloads** using `default_on: true` to protect all requests by default
|
||||
3. **Configure user tracking** to identify patterns across user sessions
|
||||
4. **Monitor violations** in Prompt Security dashboard to tune policies
|
||||
5. **Test file uploads** thoroughly with various file types before production deployment
|
||||
6. **Set appropriate timeouts** for file sanitization based on expected file sizes
|
||||
7. **Combine with other guardrails** for defense-in-depth security
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Guardrail Not Running
|
||||
|
||||
Check that the guardrail is enabled in your config:
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
- guardrail_name: "prompt-security-guard"
|
||||
litellm_params:
|
||||
guardrail: prompt_security
|
||||
default_on: true # Ensure this is set
|
||||
```
|
||||
|
||||
### Files Not Being Sanitized
|
||||
|
||||
Verify that:
|
||||
1. Files are base64-encoded in proper data URL format
|
||||
2. MIME type is included: `data:image/png;base64,...`
|
||||
3. Content type is `image_url`, `document`, or `file`
|
||||
|
||||
### High Latency
|
||||
|
||||
File sanitization adds latency due to upload and polling. To optimize:
|
||||
1. Reduce `poll_interval` for faster polling (but more API calls)
|
||||
2. Increase `max_poll_attempts` for larger files
|
||||
3. Consider caching sanitization results for frequently uploaded files
