Critical Authentication Vulnerabilities Found: Playwright Security Testing Demonstration

Critical Authentication Vulnerabilities Found: Playwright Security Testing Demonstration

🔐 The above video demonstrates a security assessment performed using Playwright automation to validate multiple authentication and session-management vulnerabilities.

🔴 Authentication Bypass Testing
🟠 Session Fixation Analysis
🔵 Cookie Security Validation
🟣 Open Redirect Assessment
⚫ CAPTCHA Protection Evaluation
🟤 Automated Security Validation using Playwright

The demonstration highlights how multiple security weaknesses can potentially be chained together to create unauthorized account access scenarios. The objective is to help security teams identify, validate, and remediate critical authentication risks before they can be exploited.

End-to-End AI Credit Risk Systems: Turning Raw Data into Instant Lending Intelligence

 

 

 Please click  Closed Captions (CC) icon in my video to read the Transcripts of my video

🟢 What’s new?
Banks are leveraging AI-powered credit risk platforms to calculate a loan applicant’s credit score within seconds, transforming traditional lending into a real-time decision system.

🔵 How it works
A modern data Lakehouse architecture integrates streaming data (via tools like Kafka), processes it with platforms like Data Bricks & Spark, and applies ML models to evaluate risk instantly.

🟣 Key innovation
The system uses multi-layered data refinement (Bronze → Silver → Gold) to convert raw data into high-quality, decision-ready insights—fueling accurate credit scoring.

🟡 Risk intelligence in action
Advanced analytics compute critical metrics like Probability of Default (PD), Loss Given Default (LGD), and Exposure at Default (EAD)—powering smarter, faster lending decisions.

🔴 Business impact
With visualization tools like Power BI, banks can deliver real-time dashboards, automated decisions, and enhanced customer experience—reducing approval time from days to seconds.

🟠 Big picture takeaway
AI + real-time data pipelines are redefining credit risk—moving from manual approvals to intelligent, end-to-end decision platforms that scale with speed and precision.

 MODERN END TO END IBRD CREDIT SCORE AI PREDICTOR FULL STACK WITH CHAT ASSISTANT APPLICATION DEVELOPMENT, TESTING, AND CI/CD

 

🔷 Development: Modular React frontend + Node proxy + FastAPI ML — component-first UX fixes and clear error propagation for robust predictions. 

 

🟩 Unit Testing: Jest + React Testing Library verify component logic and edge handling (form, chatbot, error flows). 

 

🟨 Feature / E2E: Cucumber feature specs + Playwright exercise full user journeys (form scoring, chatbot insights, internet comparison). 

 

🟥 API Smoke: Postman/Newman validate proxy ↔ ML connectivity and quick failure detection. 

 

🟪 CI Orchestration: azure-pipelines.yml automates lint → test → build → containerize → publish; uses docker-compose*.yml to reproduce environments. 

 

🟧 Health & Stability: Pipeline health/wait gates prevent flaky E2E runs; tests assert styled fallbacks (red-on-yellow) for service outages. 

🔎 Visibility: CI publishes HTML/JUnit reports and coverage (Cobertura) so regressions are traceable across test → UAT → prod.

VSCode Integration with Local MCP Server To Automate the P2P Business Process Flow in SAP S/4HANA

 

Overview: 

🔵 Integrate VS Code with a local AI LLM to automate the P2P (Procure-to-Pay) process flow in SAP S/4HANA. 

🔵 A local MCP server is created to host AI tools. 

🔵 The MCP server registers “test” as a tool for execution. 

🔵 A CLI interface is implemented to manage standard input/output (STD I/O). 

🔵 The CLI converts user commands into instructions understood by the MCP server. 

🔵 The MCP server receives the converted commands and executes the “test” tool. 

🔵 Results flow from the MCP server back through the CLI into VS Code, enabling automated workflow execution.
