Welcome to the Web Application Penetration Testing repository! This serves as a comprehensive guide to mastering Web Application Security, covering everything from foundational concepts to advanced exploitation techniques. This repository is designed for:
- Cybersecurity professionals enhancing their penetration testing skills.
- Bug bounty hunters looking to stay ahead with the latest vulnerabilities.
- Developers aiming to build secure applications by understanding attack vectors.
- CTF players practicing real-world exploitation techniques.
With hands-on labs sourced from various platforms, this repository will help you gain practical experience in Web Application Security and Bug Bounty Hunting.
- Learn Web Application Penetration Testing step by step.
- Understand the OWASP Top 10 (2025) vulnerabilities with real-world examples.
- Explore different attack techniques for server-side and client-side vulnerabilities.
- Gain insights into advanced web security threats and exploitation methods.
- Apply knowledge in practical, real-world scenarios through hands-on labs.
Getting started with web security can feel overwhelming, but the key is to learn step by step. We recommend progressing through topics at your own pace, practicing with labs as you go. If a challenge feels too tough, move forward and revisit it later with fresh insights. For structured guidance, check out our curated learning paths below.

This repository provides an in-depth analysis of the latest OWASP Top 10 vulnerabilities to ensure you understand modern web security threats.
- Ranked #1 due to 94% of applications exhibiting some form of access control issues.
- Covers 34 Common Weakness Enumerations (CWEs) related to access control flaws.
- Previously known as Sensitive Data Exposure.
- Focuses on failures in cryptographic implementations leading to data leaks or system compromise.
- Includes SQL Injection (SQLi), Cross-Site Scripting (XSS), and other code injection flaws.
- Found in 94% of tested applications.
- Emphasizes threat modeling, secure design patterns, and reference architectures.
- Often caused by misconfigured application settings, cloud services, and security controls.
- Formerly Using Components with Known Vulnerabilities.
- One of the most challenging issues to test and mitigate.
🔹 A07:2021 - Identification and Authentication Failures
- Previously Broken Authentication.
- Common misconfigurations still lead to authentication security issues.
- Includes Insecure Deserialization and risks related to CI/CD pipelines.
- Crucial for incident response and forensic investigations.
- Newly added due to increasing real-world exploitation.
Beyond OWASP Top 10, this repository covers a broad range of server-side and client-side security risks.
