A01:2025 Broken Access Control - Access control mechanisms enforce policies ensuring that users interact with systems solely within their authorized permissions. Vulnerabilities in this area typically result in unauthorized data disclosure, modification, or destruction, as well as actions exceeding defined user boundaries. Effective controls are essential for maintaining data integrity and confidentiality in government operations for government environments.

A02:2025 Security Misconfiguration - Security misconfiguration occurs when systems, applications, or cloud services are improperly secured during setup, creating exploitable vulnerabilities. Rigorous configuration management is critical to prevent exposure of sensitive information.

A03:2025 Software Supply Chain Failures - These failures involve compromises within the software development lifecycle, including building, distribution, and updates. Such risks often stem from vulnerabilities or malicious alterations in third-party code, tools, or dependencies relied upon by the system. Managing these risks is vital for ensuring trust in government software for government use cases.

A04:2025 Cryptographic Failures - All data in transit should generally be encrypted at the transport layer (OSI Layer 4). Modern computing infrastructure facilitates encryption through hardware-accelerated instructions (e.g., AES) and streamlined certificate management via services like LetsEncrypt.org or cloud provider integrations. Beyond transport layer security, organizations must identify data requiring encryption at rest and additional application-layer (OSI Layer 7) protection. Sensitive categories include passwords, financial data, health records, personally identifiable information (PII), and proprietary business secrets, particularly those subject to privacy regulations such as the EU General Data Protection Regulation (GDPR) or the Payment Card Industry Data Security Standard (PCI DSS).

A05:2025 Injection - An injection vulnerability allows attackers to insert malicious code or commands, such as SQL or shell code, into application input fields. The system may execute this untrusted input as if it were legitimate, leading to severe security breaches and operational failures.

A06:2025 Insecure Design - Insecure design encompasses weaknesses resulting from missing or ineffective control design. It is distinct from insecure implementation; while a secure design can suffer from implementation defects, an inherently insecure design cannot be remediated through code fixes alone because the necessary protective controls were never established. Factors contributing to insecure design include inadequate business risk profiling during development, leading to insufficient security requirements.

A07:2025 Authentication Failures - This vulnerability exists when attackers successfully deceive a system into authenticating as an invalid or unauthorized user. Robust authentication processes are critical for verifying identity and preventing unauthorized access to government systems.

A08:2025 Software or Data Integrity Failures - These failures occur when code and infrastructure fail to validate the trustworthiness of data or executables, treating untrusted inputs as secure. Examples include reliance on plugins, libraries, or modules from unverified sources, repositories, or content delivery networks (CDNs). Insecure continuous integration and deployment (CI/CD) pipelines that fail to perform integrity checks can introduce unauthorized code or lead to system compromise. Secure practices require verifying signatures or using similar mechanisms before consuming artifacts.

A09:2025 Security Logging & Alerting Failures  - Inadequate logging, monitoring, and alerting prevent the timely detection of attacks and hinder effective incident response. Continuous monitoring and active alerting are necessary to initiate appropriate countermeasures during security events.

A10:2025 Mishandling of Exceptional Conditions - This occurs when software fails to prevent, detect, or appropriately respond to unexpected errors or conditions, potentially causing crashes, unpredictable behavior, or security vulnerabilities. Remediation involves addressing failures in prevention, detection, and post-event response.
