OWASP Top 10 2025
The application security (AppSec) landscape is in a constant state of flux, driven by rapid technological advancements and the escalating sophistication of cyber threats. To help organizations stay ahead, the Open Worldwide Application Security Project (OWASP) produces its seminal Top 10 report. This document is not a static list of vulnerabilities but a living, evolving consensus of the most critical security risks facing web applications.
Understanding the Role of OWASP
The Open Worldwide Application Security Project (OWASP) is a global non-profit organization focused on making software security visible so that individuals and organizations can make informed risk decisions. It operates on the principles of community-driven, open-source knowledge sharing. The OWASP Top 10 is the organization’s flagship awareness tool, meticulously compiled using data from industry experts, security researchers, and security firms worldwide. Its primary function is to establish a baseline standard for secure development practices and to help teams prioritize their defensive efforts against the most impactful threats.
Defining the Next Standard: The OWASP Top 10 2025
The forthcoming OWASP Top 10 2025 is anticipated to be a significant release, reflecting a critical maturation in the understanding of software risk. It is expected to move beyond simple code-level flaws to emphasize issues arising from insecure architecture, operational complexity, and the expanding software supply chain.
While the final composition is determined by data analysis and community input, the 2025 list is structured to address the weaknesses most prevalent in modern applications built on microservices, cloud infrastructure, and extensive third-party dependencies. The anticipated categories for the 2025 report are designed to be more actionable and focused on the root causes of common security failures:
- Broken Access Control: Failures to restrict what authenticated users can access or do.
- Security Misconfiguration: Errors in hardening, cloud settings, or default setups.
- Software Supply Chain Failures: Risks introduced via third-party code, dependencies, or build tools.
- Cryptographic Failures: Insufficient protection of data in transit and at rest.
- Injection: Flaws allowing unvalidated input to be executed as commands or queries.
- Insecure Design: Lack of security controls defined before coding begins (a proactive category).
- Authentication Failures: Weaknesses in managing user identities and sessions.
- Software and Data Integrity Failures: Problems with validating the reliability and integrity of updates, critical data, or code.
- Logging & Alerting Failures: Insufficient detection and response capabilities.
- Mishandling of Exceptional Conditions: Errors in logic or design that occur during abnormal operational states (e.g., error messages exposing internal data).
Key Shifts: Comparing OWASP Top 10 (2021 vs. 2025)
Comparing the 2021 and 2025 iterations highlights how the industry’s focus has adapted to current threat models. The evolution points toward a necessary shift from fixing symptoms to addressing systemic weaknesses.
1. The Rise of Supply Chain Risk
Perhaps the most crucial shift is the emphasis on Software Supply Chain Failures. In the 2021 list, this was addressed as “Vulnerable and Outdated Components” (A06). The 2025 category broadens this scope dramatically. It acknowledges that simply updating a library is not enough; the security of the entire ecosystem—from dependency management tools (like NPM or Maven) to CI/CD pipelines—must be validated. High-profile attacks often target this trust chain, making it one of the most significant architectural risks.
2. Prioritizing Proactive Security
The category Insecure Design (A04:2021) has cemented its role in the new list. This category is distinct because it is not about a bug in the code; it’s about a missing or flawed control at the blueprint stage. For instance, a system that lacks limits on repeated failed login attempts, or an API that trusts client-side input without server-side validation, is a design flaw. The continued prominence of this category forces development teams to adopt a security-by-design approach.
3. Persistent Foundational Flaws
Certain vulnerabilities remain stubbornly common:
- Broken Access Control (A01) consistently holds the top or near-top spot across all reports. This demonstrates that developers consistently struggle with applying the principle of least privilege correctly, leading to authorization flaws.
- Security Misconfiguration (A02) has become increasingly critical. With the ubiquity of infrastructure-as-code and container orchestration, misconfigured cloud security groups, open storage buckets, or insecure default container settings are now major breach vectors, often superseding code-level injection attacks in prevalence.
4. Refinement and Consolidation
To streamline the focus, some 2021 items have been rolled into broader, more thematic categories in 2025:
| 2021 Category | Transition in 2025 |
| A10:2021 Server-Side Request Forgery (SSRF) | Rolled into Broken Access Control SSRF is fundamentally an access control bypass issue.
Focuses on secure error handling and resilience. |
| A09:2021 Security Logging and Monitoring Failures | Evolved to Logging & Alerting Failures Increased focus on active alerting and response capabilities, not just passive logging. |
This consolidation aims to simplify the message, helping teams focus their efforts on fixing the underlying security engineering discipline rather than chasing specific exploit types.
5. Key Additions:
The OWASP 2025 has two major additions to the list.
Software Supply Chain Failures(New)
- It provides an in-depth explanation of the category “Vulnerable and Outdated Components.”
- Includes dependency confusion, malicious packages, and compromised CI/CD pipelines.
Mishandling of Exceptional Conditions(New)
- It includes poor error handling and unvalidated exceptions leading to leaks or crashes.
- Example: Stack traces exposing sensitive data.
Conclusion
The evolution from the 2021 to the 2025 OWASP Top 10 reflects an application security discipline that is maturing beyond chasing code bugs. It signals a necessary transition where security must be an integrated part of the software architecture and operational model, especially considering the complexity introduced by cloud, APIs, and the global software supply chain. Organizations that successfully adapt will not only focus on eliminating injection and access control flaws but will also actively embed security controls into the design phase and rigorously vet their third-party dependencies. The 2025 list is a clear roadmap for building resilient, trustworthy applications in the face of continuous digital threats.
