OWASP Top 10 2025: Understanding common web app vulnerabilities and security risks

What is the OWASP Top 10 2025?

The OWASP Top 10 is a standard reference for the most critical security risks to web applications. Updated periodically to reflect current threats, the 2025 edition captures changes in attack patterns, technology use, and real-world data from security professionals worldwide.

Key highlights from the OWASP Top 10 2025 include:

• Broken access control remains the leading vulnerability, emphasizing the need for strict authorization practices.
• Cryptographic failures have replaced "sensitive data exposure," broadening the focus beyond data leaks.
• Insecure design appears for the first time, pointing to the need for security considerations from the planning phase.
• Server-side request forgery (SSRF) has gained its own category, reflecting its growing impact.

Understanding these changes is vital for developing secure applications and aligning internal security audits with industry standards. Read more about the importance of security habits here.

Common web app vulnerabilities in the OWASP Top 10 2025

Many of the vulnerabilities featured in the OWASP Top 10 2025 fall into recurring patterns developers and security teams must address. These common web app vulnerabilities include:

1. Broken access control

Failure to properly enforce user roles and permissions can allow unauthorized access to sensitive resources. Examples include:

• Forced browsing to unauthorized pages
• Modification of URL parameters to access restricted data
• Bypassing access controls via APIs

Mitigation: Implement strong access control mechanisms, perform regular access audits, and enforce least privilege principles.

2. Injection flaws

While SQL injection is the most notorious, the category also covers NoSQL, OS command, and LDAP injections. Attackers exploit these flaws to manipulate queries and execute unauthorized actions.

Mitigation: Use parameterized queries, input validation, and ORM libraries.

3. Security misconfigurations

Default settings, incomplete setups, or exposed administrative interfaces can expose applications to unnecessary risk.

Mitigation: Harden server configurations, disable unused features, and perform regular vulnerability assessments.

Addressing OWASP security risks: proactive strategies

Responding to the OWASP Top 10 2025 requires a proactive, layered defense strategy. Organizations should implement the following practices:

1. Secure development lifecycle (SDL)
   
   • Integrate security testing and reviews into every phase of development.
2. Continuous vulnerability detection
   
   • Use automated scanning tools to regularly identify and prioritize vulnerabilities.
3. Premium pentesting
   
   • Complement automated scans with expert-driven ethical hacking to uncover logic flaws, insecure designs, and emerging threats. Check out our Premium Pentesting and Automated Scans, and how this could be beneficial for your organization.
4. Threat modeling
   
   • Analyze application architectures to identify security weaknesses before they are exploited.
5. Security awareness training
   
   • Educate developers and operational teams on secure coding practices and common attack vectors. 

Why the OWASP Top 10 2025 matters more than ever

Web applications continue to expand in complexity, integrating APIs, cloud services, and third-party components. This growing attack surface makes consistent monitoring and fast remediation a necessity.

Organizations that align their security practices with the OWASP Top 10 2025 will not only reduce the likelihood of breaches but also improve regulatory compliance, customer trust, and business resilience.

At Strike, we specialize in helping companies detect and fix vulnerabilities before attackers can exploit them. Our combination of premium pentesting and continuous automated scanning ensures that your applications stay ahead of the OWASP security risks highlighted in the latest Top 10 list.
