Vibe coding, building software by prompting and accepting output without reading it closely, is fine for throwaway work that touches nothing sensitive. It is a poor choice for anything that handles other people's data, money, authentication or production systems, or that will outlive the week.
Three questions to ask
- What can it reach? Local files only, or a database, an API with real keys, customer records?
- Who uses it? Just you, your team, or the public?
- How long will it live? A one time script, or something people will depend on in six months?
If the answers are "nothing sensitive, just me, this afternoon", go ahead. Each step up the scale needs more review.
The green zone
- A script that renames files on your own machine.
- A prototype to test an idea, run locally, with fake data.
- A throwaway chart or data cleanup for your own analysis.
Even here, do not paste real credentials into prompts and do not let the tool install packages without you seeing the names.
The yellow zone
- An internal tool used by colleagues.
- A small automation with access to a shared drive or ticket system.
Read the code that handles input, permissions and secrets. Run a dependency and secret scan. Put it behind your normal login. Name an owner.
The red zone
- Anything with customer data, payments or health information.
- Authentication, authorization and session handling.
- Code that runs with production credentials or in a CI pipeline.
- Anything exposed to the internet.
Here, AI can draft, but a person who understands the code must review and own it. Stanford researchers found participants using an AI assistant wrote significantly less secure code and were more confident in it, which is the exact failure vibe coding invites.
Prototypes that become products
The usual way vibe coding goes wrong is not the first version. It is the prototype that quietly gains users. Set a rule: when a prototype gets real data or a real user, it gets a review, a scan and an owner.
A free scan at gold.safeguard.sh/scan is a cheap first check on a prototype's dependencies.
A quick promotion rule
Write a one line rule where everyone can see it: any project that gets real user data, a real login or a production credential must pass a review before the next release. The rule is cheap, it removes the argument in the moment, and it catches the prototype that quietly became a product. Put the project owner name in the readme so someone is responsible.
Quick check
Is vibe coding always a security risk?
No. The risk scales with what the code can reach and who relies on it. A local throwaway has little exposure; a public app with user data has a lot.
