The Open Worldwide Application Security Project (OWASP) is a global, open community that provides guidance, tools, and best practices for improving application security. The OWASP Top 10 is the most widely recognized awareness document for developers, security professionals, and organizations to understand the most critical web application security risks. Compared to OWASP Top 10:2021, the … Read more
Mishandling of Exceptional Conditions is a new category introduced in the OWASP Top 10:2025. It focuses on applications that fail to properly handle unexpected errors, exceptions, or abnormal conditions. Poor exception handling can expose sensitive information, cause application crashes, create security vulnerabilities, or even allow attackers to perform further attacks. Applications should always handle errors … Read more
Security Logging and Alerting Failures is ranked A09 in the OWASP Top 10:2025. Even if an application has strong security controls, they become ineffective if attacks are not detected. Without proper logging, monitoring, and alerting, organizations may remain unaware of security incidents for months or even years, allowing attackers to steal sensitive information without interruption. … Read more
Software or Data Integrity Failures is ranked as A08 in the OWASP Top 10: 2025. This security risk occurs when an application fails to verify the integrity and authenticity of software, code, updates, or data before using them. If developers blindly trust external components without validation, attackers can introduce malicious code that compromises the entire … Read more
Authentication is one of the most critical security mechanisms in any web application. It ensures that only legitimate users can access protected resources and perform authorized actions. Authentication Failures occur when weaknesses in the authentication or session management process allow attackers to impersonate valid users, gain unauthorized access, or compromise user accounts. In the OWASP … Read more
Modern application security is not only about fixing coding errors and patching vulnerabilities. Many serious security issues originate much earlier—during the planning and design phase of an application. To address this concern, OWASP introduced Insecure Design as a separate category in the OWASP Top 10 in 2021, and it continues to be a critical risk … Read more
Injection vulnerabilities remain one of the most dangerous and widely tested security weaknesses in modern web applications. Listed as A05: Injection in the OWASP Top 10:2025, these vulnerabilities occur when untrusted user input is sent to an interpreter and executed as part of a command or query due to insecure application design. Attackers exploit injection … Read more
Cryptographic Failures (A04) remain one of the most critical security weaknesses highlighted in the OWASP Top 10 (2025). This category focuses on the improper implementation, weak usage, or complete absence of encryption mechanisms that protect sensitive data in modern applications. When cryptography is misconfigured or outdated, attackers can easily intercept, decode, or manipulate sensitive information … Read more
Software Supply Chain Failures (A03) have emerged as one of the most critical cybersecurity concerns in modern software development. Organizations today rely heavily on third-party libraries, open-source packages, APIs, cloud services, operating systems, and external vendors to build and maintain applications. While these dependencies accelerate development, they also introduce significant security risks if not properly … Read more
One of the major vulnerabilities listed at number 2 is Security Misconfiguration (A02) in OWASP Top 10:2025. This vulnerability occurs when an application, server, framework, cloud service, or database is configured improperly, leaving security gaps that attackers can exploit. Security misconfiguration is one of the most common causes of application compromise because many organizations deploy … Read more
