The OWASP Top 10 has consistently served as a baseline for application security. Despite its long-standing presence, recent events in June 2026 confirm that every category on the list remains actively exploited in the wild.
Current Threats Map to Every OWASP Top 10 Category
Supply chain attacks, a recurring theme, directly illustrate several OWASP categories. A recent incident involving the Bitwarden CLI npm release, where a compromised GitHub Action inserted a credential-stealing loader, is a textbook example of A08 Software and Data Integrity Failures and also touches on A06 Vulnerable and Outdated Components. The same month saw an Exchange 0-Day and a malicious npm worm, again highlighting A06 and A08.
Server-Side Request Forgery (A10) surfaced with a high-severity SSRF bug (CVE-2026-45401) in Open WebUI. This vulnerability allowed attackers to bypass URL validation and access internal services, demonstrating a direct exploitation of A10.
Security Misconfiguration (A05) continues to be a critical issue. An exposed AWS S3 bucket used by the unofficial UK Visa portal leaked over 100,000 documents, a clear instance of A05. Similarly, Iranian actors exploited unprotected Automatic Tank Gauge systems at gas stations, leveraging devices with no passwords—another case of A05.
Identification and Authentication Failures (A07) and Broken Authentication (A02) also saw significant exploitation. The University of Oxford's CareerConnect service breach, where attackers accessed names, emails, and encrypted passwords via compromised SSO credentials, reflects A07. Furthermore, a CISA contractor's public GitHub repository exposed GovCloud keys and plaintext passwords, pointing to poor credential management and aligning with A02 and A07.
Broken Access Control (A01) and Injection (A03) remain prevalent. CISA added a critical command-injection flaw in the AI gateway LiteLLM (CVE-2026-42271) to its KEV catalog, indicating active exploitation of A01 and A03.
These incidents collectively confirm that the OWASP Top 10 is not an academic exercise but a living checklist for immediate remediation efforts.
Extending the Top 10 for AI-Centric Environments
While the classic Top 10 controls remain foundational, OWASP is now urging organizations to extend them with AI-centric governance and risk-tiered application. At the OWASP GenAI Security Summit on June 4, 2026, the organization unveiled its new Agentic AI Security Maturity Framework.
This framework defines maturity levels, from "Shadow AI" to fully custom in-house agents, and maps the Top 10 controls to each risk tier. The intent is to ensure that lightweight AI copilots receive proportionate safeguards, while complex multi-agent systems are subjected to full-scale controls. This guidance emphasizes operationalizing security measures that scale with the complexity and criticality of AI systems being deployed.
The framework, also known as the 'Enterprise Adoption Maturity Model,' acknowledges that AI-driven development is inevitable and should be governed rather than blocked. It provides a structured approach to integrate security practices into AI development and deployment, ensuring that established application security principles are not overlooked in the rush to adopt new technologies.
For security teams, this means treating the OWASP Top 10 as a dynamic, rather than static, reference. Integrate the new Agentic AI Security Maturity Framework into your risk assessments for any AI components, ensuring that your existing application security controls are appropriately applied and extended to cover AI-specific risks commensurate with their maturity and impact.
