Vibe Coding: A Pentester’s Dream

The article explores “vibe coding,” a style of software development where AI (via chat-interfaces in IDEs) generates code based on prompts with minimal human oversight. The NetSPI team built a vibe-coded web application (a dental services app) and then assessed its security via AI audits and manual penetration testing. They found that while AI could flag and remediate some vulnerabilities (e.g. password hashing, injection protections), it frequently introduced or overlooked serious issues—especially in authorization logic, business rules, and fine-grained access control (e.g. IDOR and role-based flaws). The piece concludes that as AI coding becomes more common, organizations must remain proactive with rigorous testing, especially of authorization, and not blindly trust AI defaults.

KEVIntel: Real-Time Intelligence on Exploited Vulnerabilities

KEVIntel is a dynamic platform providing up-to-date information on known exploited vulnerabilities (KEVs). It aggregates data from over 50 public sources, including CISA, and enriches each entry with metadata such as EPSS scores, online mentions, scanner inclusion, and exploitation status. The platform aims to serve as an early warning system, offering insights even before official publications. KEVIntel supports various formats like JSON, CSV, and RSS, facilitating integration into security operations. These entries include CVSS scores, exploit status, and links to proof-of-concept code, aiding organizations in prioritizing remediation efforts.   https://kevintel.com/

OWASP SAMM Skills Framework Enhances Software Security Roles

The OWASP SAMM Skills Framework, introduced on February 9, 2025, is a new initiative donated by Siemens to enhance software security practices within organizations. This framework assigns specific responsibilities to SAMM (Software Assurance Maturity Model) streams, clarifying which roles are involved in advancing each stream. It provides guidance on the necessary skills and training for each role, aligning SAMM-related activities with appropriate stakeholders and their required competencies. This alignment helps organizations identify the right personnel and visualize shared responsibilities, ensuring a structured approach to secure product development. Implementing the OWASP SAMM Skills Framework involves several key steps. Organizations must first map responsibilities to roles, ensuring each task is assigned to the right individual. Next, they must evaluate and align stakeholders with specific SAMM streams, validating that those assigned understand and accept their roles in advanci...
