Remove Flask debug mode from all test files (5 instances) - Sanitize clear-text logging in security deployment script - Sanitize API key exposure in debug model loading script - Add exception sanitization utility to prevent information exposure - Apply sanitization to 6 critical exception exposure points in unified API - All changes maintain functionality while eliminating security risks - Ready for security review and testing --- deployment/cloud-run/test_minimal_swagger.py | 2 +- deployment/cloud-run/test_routing_minimal.py | 2 +- deployment/cloud-run/test_swagger_debug.py | 2 +- deployment/cloud-run/test_swagger_no_model.py | 2 +- scripts/deployment/security_deployment_fix.py | 24 ++++++++++++++-- scripts/testing/debug_model_loading.py | 2 +- src/unified_ai_api.py | 28 ++++++++++++++----- 7 files changed, 48 insertions(+), 14 deletions(-) diff --git a/deployment/cloud-run/test_minimal_swagger.py b/deployment/cloud-run/test_minimal_swagger.py index eb19bfe61..14b6c1e8e 100644 --- a/deployment/cloud-run/test_minimal_swagger.py +++ b/deployment/cloud-run/test_minimal_swagger.py @@ -44,4 +44,4 @@ def get(self): print("- http://localhost:5003/docs (should work)") print("- http://localhost:5003/api/health (should work)") -
