Vibe coding represents a fundamental shift in software development, moving the developer's role from a writer of syntactic code to an orchestrator of semantic intent. Coined in February 2025, the term describes a workflow where developers engage in a conversational loop with an AI, expressing desired outcomes in natural language and allowing the AI to translate that intent into executable code. This approach moves the developer to a higher level of abstraction, focusing on the "what" (the goal) rather than the "how" (the specific implementation details).
Vibe coding fundamentally breaks traditional application security models by creating a development culture where pre-production security tools are often bypassed entirely. The core philosophy of "pure" vibe coding prioritizes speed and rapid iteration above all else, creating a workflow that is incompatible with the friction of legacy security gates like static scanning. Developers engaged in this rapid, conversational loop focus on generating and refining code, meaning vulnerabilities are inevitably pushed into the production environment without any prior security validation.
This practice makes the runtime environment the first and best line of defense. Because the code has not been vetted, the live application becomes the proving ground for its security. This leads to the deployment of subtle but critical vulnerabilities in business logic that often go undetected by traditional scanners and only manifest with live user traffic.
Furthermore, vibe coding massively scales the long-standing problem of "Shadow IT." It empowers non-technical developers to rapidly create and deploy applications, all completely outside the purview of IT and security teams. These applications, built without any security oversight, create a vast, unmanaged, and invisible attack surface running live in the enterprise. This means SecOps and SOC teams are tasked with defending a growing portfolio of production applications they may not even know exist, making runtime visibility and protection more critical than ever.
Vibe coding operates as a tight, iterative, and conversational loop between a human and an AI agent. This process typically takes place within specialized platforms designed for full application generation or through AI assistants that function as powerful pair programmers within a developer's existing coding environment.
The core workflow is a continuous cycle. A developer begins by describing a goal with a high-level prompt. The AI then generates an initial block of code. The developer immediately executes it to observe its behavior. Based on the output, the developer provides feedback—often by simply pasting an error message or giving a refinement in natural language. The AI refines the code based on this feedback, and the loop repeats until the desired functionality is achieved.
The term "vibe coding" is often used ambiguously, creating significant risk by conflating two very different methodologies. On one end of the spectrum is "pure" vibe coding, the literal interpretation of "forgetting the code exists." It is characterized by the uncritical acceptance of AI-generated code without thorough review, testing, or a deep understanding of its mechanics. This approach prioritizes speed above all else and carries catastrophic risk in production systems. In contrast, responsible AI-assisted development is the professional application of the concept, where the AI serves as a "co-pilot" to a human developer who remains in full control. In this model, the developer guides the AI but critically reviews, tests, and takes complete ownership of all generated code, integrating AI's productivity gains without abandoning security standards.
Undisciplined vibe coding leads to systemic insecurity, as AI models trained on flawed public code can reproduce vulnerabilities. Research from institutions like New York University and benchmark analyses from BaxBench confirm this, finding that 40% to 62% of AI-generated code contains security flaws. This is directly linked to the creation of complex logical flaws that function as intended during testing but are exploitable at runtime, rendering traditional "shift-left" scanning insufficient.
The accessibility of these tools also fuels enterprise-scale Shadow IT, empowering non-technical users to create applications with sensitive data outside of security governance. This creates a massive, invisible attack surface that security teams are unprepared to defend.
Finally, this practice compounds software supply chain risk, as AIs may recommend vulnerable third-party libraries or introduce code with restrictive licenses. Over-reliance on AI can also cause an erosion of foundational developer skills, creating a dangerous "comprehension gap" where teams can no longer effectively debug or respond to incidents in production.
Mitigating the risks of vibe coding is not about banning AI tools but about implementing a culture of responsible AI-assisted development supported by modern security controls. The most critical element is establishing a framework of developer accountability and best practices. This means mandating human oversight where developers review, test, and own all AI-generated code. It also involves training developers to decompose complex problems into smaller, more manageable prompts and to use version control systems like Git to create frequent checkpoints, allowing for a quick rollback if an AI introduces a flaw.
As development becomes more decentralized, centralized security policy and governance become paramount. A central platform for managing security policies ensures that all applications, regardless of how they were built, adhere to the same standards for vulnerability management and risk. This provides security teams with essential visibility and control, allowing them to enforce rules and monitor the security posture of the entire application portfolio from one place.
Finally, since vibe coding creates vulnerabilities and often avoids pre-production testing, runtime security monitoring is no longer optional. Continuous monitoring of live applications is the only way to gain visibility into how AI-generated code actually behaves and to detect attacks against vulnerabilities that were unaddressed during development.
Vibe coding challenges traditional AppSec tools by creating a development workflow that is too fast and iterative for their designed purpose. The core issue is that the rapid, conversational nature of vibe coding often bypasses these pre-production requirements. For instance, SAST (Static Application Security Testing) tools are often perceived as too slow for the vibe coding loop, while SCA (Software Composition Analysis) checks are missed entirely, allowing vulnerable dependencies introduced by AI to be pushed to production. Even DAST (Dynamic Application Security Testing), which tests the running application, can struggle to identify complex flaws embedded deep within the AI-generated business logic. Because these pre-production tools are frequently sidestepped or insufficient for the novel risks, a new approach is required to provide a safety net for live, running applications.
The core challenge of vibe coding is that it produces insecure code at a velocity that outpaces—and often entirely bypasses—traditional security processes, placing unaudited code directly into production. Contrast Security is uniquely positioned to address this challenge by providing a safety-net where it matters most: in the running application.
For vulnerabilities created by vibe coding, Contrast’s Application Vulnerability Monitoring (AVM) provides essential visibility at runtime. Since the vibe coding process often circumvents pre-production security checks, applications are deployed with unknown and unverified risks. Contrast's instrumentation-based approach works inside the live application, allowing AVM to identify vulnerabilities as the code actually executes. This provides real-world evidence of risk and closes the critical visibility gap created when traditional security gates are skipped.
For attacks targeting these new flaws, Contrast’s Application Detection and Response (ADR) offers a critical layer of defense. ADR monitors and protects applications from attacks in real-time. When an attacker attempts to exploit an insecure, AI-generated function, ADR can detect and block the attack instantly, preventing a breach even if the vulnerability was unknown. This provides a crucial compensating control for the massive, unmanaged attack surface created by Shadow IT and vibe coding.
By focusing on the runtime environment, Contrast provides the definitive view of application risk and the most effective protection against it, enabling development teams to innovate with AI safely.
