Understanding the OWASP Top 10 2025 for Modern Application Security

In the world of application security, vulnerabilities are always a moving target. As modern applications keep becoming increasingly API-driven, cloud-native, and dependent on third-party services, the attack surface has expanded dramatically. For years, the OWASP Top 10 has served as the North Star for security professionals, providing a consensus-based ranking of the most critical web application security risks.

In 2025 the framework was updated to reflect new attack vectors and shifting architectural trends. For organizations using Detectify, understanding these changes is vital for maintaining a robust security posture. In this blog, we’ll break down the OWASP Top 10: 2025, explore how Detectify helps you achieve compliance, and identify where you might need complementary tools.

What is the OWASP Top 10?

OWASP is a non-profit organization aiming to improve software security. Their Top 10 is a critical resource that highlights the most prevalent threats that expose your applications to attack. From data breaches to unauthorized access, these vulnerabilities can have devastating consequences. Understanding these risks is the first step in building a robust security posture. The OWASP Top 10 is regularly updated to reflect the evolving threat landscape. These updates highlight the dynamic nature of applications and the most critical risks that they face today.

In the world of AppSec, this document is more than just a list: it serves as a baseline for auditors, procurement teams, and major compliance frameworks like PCI DSS. If your application can defend against the OWASP Top 10, you have built a good foundation for security.

What Changed in the OWASP Top 10 2025?

The application security landscape has evolved dramatically since the last major OWASP update in 2021: 

• A Brand New Category (A10:2025 – Mishandling of Exceptional Conditions): Making its debut this year, this category addresses how applications behave when things go wrong. It highlights the dangers of applications “failing open” under pressure, causing logical errors, or leaking sensitive debugging information through verbose error messages.
• Consolidation and Expansion of Access Control (A01:2025): Broken Access Control remains a massive threat, but its scope has expanded. Recognizing how attackers exploit interconnected systems, OWASP has formally integrated Server-Side Request Forgery (SSRF) and Open Redirects into this category.
• A Deeper Focus on the Supply Chain (A03:2025): What was previously focused heavily on “Vulnerable and Outdated Components” has matured into Software Supply Chain Failures. This shift acknowledges that security risks don’t just come from old code, but from vulnerabilities introduced throughout the entire CI/CD pipeline, build tools, and third-party dependencies.

The OWASP Top 10 2025 Breakdown

A01:2025 – Broken Access Control

What it covers: Restrictions on what users are allowed to do are not properly enforced. This allows attackers to access unauthorized functions or data. In the 2025 update, this category now includes Server-Side Request Forgery (SSRF) and Open Redirects.

• Detectify Coverage: Detectify finds authentication bypass, authorization flaws, path traversal, CSRF, and open redirects. Notably, Detectify has 181 specific tests for SSRF.
• Key CWEs: CWE-22, CWE-284, CWE-287, CWE-918 (SSRF), CWE-601.

A02:2025 – Security Misconfiguration

What it covers: Incorrect security hardening across the application stack. This includes default configurations, verbose error messages that leak data, and XML External Entity (XXE) vulnerabilities.

• Detectify Coverage: Full. Scans identify default credentials, exposed admin panels, directory listings, and header misconfigurations.
• Key CWEs: CWE-16, CWE-200, CWE-611.

A03:2025 – Software Supply Chain Failures

What it covers: This expands on the previous “Vulnerable and Outdated Components” category. It addresses breakdowns in building, distributing, or updating software, including malicious third-party dependencies.

• Detectify Coverage Full platform capability. Rather than just passively mapping software versions to known CVE lists, which often leads to false positives, Detectify uses a fully payload-based approach across all products to actively test and verify if you are actually vulnerable. This is powered by Alfred AI for rapid CVE testing, and a Crowdsource community of ethical hackers to build active test modules for critical, non-CVE security flaws and custom exploits.
• Key CWEs: Component detection + CVE-specific payload tests.

A04:2025 – Cryptographic Failures

What it covers: Failures in cryptography that lead to the exposure of sensitive data. This often involves weak encryption or transmitting data in cleartext.

• Detectify Coverage: Detectify tests for weak encryption, cleartext transmission, and TLS/SSL configuration flaws.
• Key CWEs: CWE-326, CWE-312, CWE-319.

A05:2025 – Injection

What it covers: User-supplied data is sent to an interpreter as part of a command or query (e.g., SQL, NoSQL, OS commands), tricking the application into executing unintended actions.

• Detectify Coverage: Comprehensive testing for SQLi, XSS, OS Command Injection, and Template Injection.
• Key CWEs: CWE-89, CWE-79, CWE-78, CWE-94.

A06:2025 – Insecure Design

What it covers: Architectural flaws that cannot be fixed by implementation alone. This focuses on risks that must be addressed during the design phase.

• Detectify Coverage: As a black-box, “from-the-outside” DAST platform, Detectify can detect the visible consequences of insecure design (such as unrestricted file uploads). While some internal, agent-based DAST solutions can monitor on-server activities, like catching cleartext data storage on a disk, true architecture and logic flaws are best addressed early during the design phase using Threat Modeling.
• Key CWEs: CWE-434, CWE-522.

A07:2025 – Authentication Failures

What it covers: Weaknesses in session management or credential validation that allow attackers to compromise user identities.

• Detectify Coverage: Detectify tests for various cases of improper authentication and use of default credentials.
• Key CWEs: CWE-287, CWE-306, CWE-613.

A08:2025 – Software or Data Integrity Failures

What it covers: Code and infrastructure that fails to protect against integrity violations, such as insecure deserialization of data from untrusted sources.

• Detectify Coverage: Detectify provides specific modules for insecure deserialization detection and integrity verification via various injection assessments (given our black-box testing approach).
• Key CWEs: CWE-502, CWE-345.

A09:2025 – Security Logging and Alerting Failures

What it covers: Insufficient logging or monitoring that prevents organizations from detecting and responding to active breaches.

• Detectify Coverage: As a DAST tool, Detectify can find information leaks via logs, but assessing the completeness of your internal logging infrastructure requires internal audits.

A10:2025 – Mishandling of Exceptional Conditions

What it covers: New for 2025. This category covers improper error handling, logical errors, or “failing open” when the application encounters an abnormal state.

• Detectify Coverage: Detectify identifies verbose error messages and improper responses to exceptional conditions.
• Key CWEs: CWE-209, CWE-755.

Detectify serves as your frontline defense by providing comprehensive, automated coverage for the most exploitable OWASP categories, including Access Control, Misconfigurations, and Injection. To achieve a more complete security posture, Detectify’s runtime protection is best paired with other practices like SAST, Threat Modeling (A06) for early design logic, SCA (A03) for deep library inventory, and SIEM (A09) for internal logging requirements.
