This allowed attackers to spoof their IP address by supplying a fake `X-Forwarded-For` header, bypassing the rate limits. +**Learning:** Manual parsing of proxy headers is dangerous. Applications should rely on the web server or ASGI server (like Uvicorn/Gunicorn) to handle proxy headers securely. Uvicorn, for example, has `--proxy-headers` and `--forwarded-allow-ips` options to trust specific upstream proxies. +**Prevention:** +1. Avoid manual parsing of `X-Forwarded-For` in application code. +2. Use `request.client.host` provided by Starlette/FastAPI, which is populated securely by the ASGI server. +3. Configure the deployment environment (Uvicorn/Nginx) to handle proxy headers and trust only known proxies. +4. If manual parsing is absolutely necessary (e.g. complex multi-proxy setup not supported by server), validate the upstream IP against a strict allowlist of trusted proxies. diff --git a/app/api/rapidapi/redact.py b/app/api/rapidapi/redact.py index 9b70009..90761da 100644 --- a/app/api/rapidapi/redact.py +++ b/app/api/rapidapi/redact.py @@ -5,16 +5,12 @@ """ import time + from fastapi import APIRouter -from app.models.rapidapi_schemas import ( - RapidAPIRedactRequest, - RapidAPIRedactResponse, - RedactedItem -) -from app.services.redaction import redact_text, get_entity_score +from app.models.rapidapi_schemas import RapidAPIRedactRequest, RapidAPIRedactResponse, RedactedItem from app.services.json_processor import process_json_with_mode - +from app.services.redaction import redact_text router = APIRouter(prefix="/v1", tags=["Main API"]) @@ -103,7 +99,7 @@ ) async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactResponse: """Redact PII entities in the provided text or JSON. - + This endpoint is designed for RapidAPI integration and provides: - Flexible input (text or JSON) - Flexible redaction modes (mask/placeholder) @@ -112,10 +108,10 @@ async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactRespo - Processing time measurement """ start_time = time.perf_counter() - + # Convert entities filter to list of strings if provided entities_filter = list(request.entities) if request.entities else None - + if request.is_json_mode: # JSON mode redacted_data, json_entities = process_json_with_mode( @@ -124,9 +120,9 @@ async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactRespo mode=request.mode, entities_filter=entities_filter ) - + processing_time_ms = (time.perf_counter() - start_time) * 1000 - + items = [ RedactedItem( entity_type=e.type, @@ -137,7 +133,7 @@ async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactRespo ) for e in json_entities ] - + return RapidAPIRedactResponse( redacted_text=None, redacted_json=redacted_data, @@ -152,9 +148,9 @@ async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactRespo entities_filter=entities_filter, mode=request.mode ) - + processing_time_ms = (time.perf_counter() - start_time) * 1000 - + items = [ RedactedItem( entity_type=item.entity_type, @@ -165,7 +161,7 @@ async def rapidapi_redact(request: RapidAPIRedactRequest) -> RapidAPIRedactRespo ) for item in redacted_items ] - + return RapidAPIRedactResponse( redacted_text=redacted_text_result, redacted_json=None, diff --git a/app/api/v1/detect.py b/app/api/v1/detect.py index 2dd5464..46e0e06 100644 --- a/app/api/v1/detect.py +++ b/app/api/v1/detect.py @@ -1,20 +1,18 @@ """Detect endpoint - find PII without modifying text or JSON.""" from typing import Union + from fastapi import APIRouter -from fastapi.responses import JSONResponse from app.models.schemas import ( - TextRequest, - UnifiedRequest, - DetectResponse, - DetectJsonResponse, DetectedEntity, - JsonFieldEntity + DetectJsonResponse, + DetectResponse, + JsonFieldEntity, + UnifiedRequest, ) -from app.services.pii_detector import get_detector from app.services.json_processor import detect_json - +from app.services.pii_detector import get_detector router = APIRouter(tags=["PII Detection"]) @@ -80,22 +78,22 @@ For JSON mode, each entity includes a `path` field showing its location (e.g., `"user.name"`).
