TL;DR: AppSec Santa found that about 1 in 4 AI-generated code samples contained at least one confirmed OWASP vulnerability, with mobile apps facing extra exposure because client-side execution on untrusted devices defeats many web-focused AppSec checks, according to NowSecure. AI-assisted development speeds delivery, but it also scales insecure patterns faster than conventional review can catch them.
NHIMG editorial — based on content published by NowSecure: AI-generated code is widening mobile app security gaps
By the numbers:
- approximately 1 in 4 code samples generated by leading AI assistants contained at least one confirmed OWASP vulnerability
Questions worth separating out
Q: How should teams validate AI-generated mobile code before release?
A: Teams should validate AI-generated mobile code against mobile-specific security standards, then test authenticated flows that exercise token handling, local storage, and backend API access.
Q: Why do mobile apps make AI-generated vulnerabilities harder to control?
A: Mobile apps execute on untrusted devices, so attackers can inspect binaries, intercept traffic, and manipulate runtime behaviour.
Q: What do teams get wrong about securing AI coding assistants?
A: Teams often focus on code output and ignore the agent boundary, where file reads, tool outputs, and external content shape the next action.
Practitioner guidance
- Make MASVS and MASWE release gates non-optional Require every AI-generated mobile build to pass controls mapped to mobile storage, certificate handling, runtime integrity, and platform interaction before promotion.
- Test authenticated user journeys in every mobile security scan Prioritise login flows, session handling, token exchange, and API calls that only appear after authentication, because that is where AI-generated logic most often leaks data or trust.
- Treat secrets in mobile code as immediately exploitable Inventory embedded keys, tokens, and configuration values in client packages and remove any assumption that mobile binaries can safely conceal sensitive material.

AI-generated mobile code creates a verification gap, not just a development-speed problem. The core issue is that code produced by assistants can be syntactically correct, pass QA, and still fail security verification. That shifts AppSec from a defect-finding exercise to a governance problem about what gets trusted in the pipeline. For mobile programmes, the control question is whether generated logic is validated against MASVS and MASWE before it reaches a device, not whether the code compiles.
A question worth separating out:
Q: What is the difference between ASVS and MASVS for application security?
A: ASVS provides a rigorous verification baseline for web and API applications, while MASVS applies similar discipline to mobile controls such as binary hardening, runtime integrity, and platform interaction security. If the code will ship in a native mobile app, MASVS is the more relevant standard for release governance.
