What you actually need to worry about, and what you can safely ignore.

Hacker News ran a story titled "Vibe Coding Is a Security Disaster That Is About to Happen." It gained significant traction, and the security concerns it raised are real. But reading it carefully, most of the risks it describes apply to people building consumer-facing web applications with user accounts, payment processing, and sensitive data at scale.
Most marketers are not building consumer SaaS. They are building their first tool as an internal solution: reporting scripts, campaign audit dashboards, data integrations, local automation tools. The risk profile is completely different.
Here is a practical breakdown of what to worry about and what to skip.
Key Takeaways
Claude Code will sometimes write credentials directly into code files during development. If you push that file to GitHub - even a private repo - those credentials can be exposed. Always store credentials in environment variables or a .env file that is listed in .gitignore. Ask Claude Code: "Move all credentials to environment variables and add .env to .gitignore."
When Claude Code sets up API access, it often requests broad permissions because that is the path of least resistance. For a Google Ads reporting script, you only need read access - not the ability to modify campaigns. Always use the minimum permission scope required. Ask Claude Code: "What is the minimum permission scope this script needs? Set it up with read-only access."
Some Claude Code sessions suggest libraries or logging services that send telemetry data externally. For tools handling client ad data or financial metrics, review what data leaves your machine. Ask Claude Code: "Does this code send any data to external services besides the APIs I specified? If so, remove those connections."
Scripts that make too many requests too quickly can get your IP blocked or, worse, violate a platform's terms of service in a way that affects your account. Ask Claude Code to add rate limiting and request delays to any scraper: "Add a 2-second delay between requests and respect robots.txt."
Any script that writes data back to Google Ads or Meta (changing bids, pausing campaigns, adjusting budgets) should be tested on a single low-spend campaign before running account-wide. Run it in read-only mode first, verify the output looks right, then enable write access for a limited test.
Most of the vibecoding security discourse is about risks that apply to consumer applications, not internal marketing tools. If you are building tools that run locally and only you use, you can deprioritize:
SQL injection - only relevant if your tool has a web-facing input form with a database backend
Authentication and session management - only relevant if other users log in to your tool
XSS vulnerabilities - only relevant if untrusted users can submit content your tool displays to others
GDPR/data compliance at scale - for tools only you run on data you already control, this is standard data handling, not a new risk
Before you run any new tool Claude Code builds for you, spend five minutes asking these questions:
Are any credentials or API keys hardcoded in the script? If yes, move them to environment variables.
Does the script write anything back to a live platform (bids, campaigns, posts)? If yes, test on a single low-risk item first.
Does the script pull data that is confidential or client-specific? If yes, confirm it is not logging that data to a file that could be accidentally shared.
Is there a .gitignore file if this is in a git repository? Check that .env and any credential files are excluded.
If this is a scraper, is there a delay between requests? Make sure it is not hitting any server hard enough to cause problems.
Yes, with a five-minute review before running any new tool. The security risks that concern developers - SQL injection, XSS, authentication flaws - apply to consumer-facing apps, not internal marketing scripts. The two real risks for marketers are API credentials in plaintext and running write-access scripts on live ad accounts without testing first.
Only if your tool has a web-facing input form connected to a database backend and receives submissions from untrusted users. For local reporting scripts, campaign audit tools, and data integrations that only you run, SQL injection is not a meaningful risk. Focus your review time on credential handling and API permission scope instead.
Store all credentials in a .env file and add that file to .gitignore before your first git commit. Claude Code will sometimes write credentials directly into code during development - this is the most common security mistake in vibecoded tools. Ask Claude Code: "Move all credentials to environment variables and add .env to .gitignore."
Running a write-access script on a live ad account before verifying the output. Any script that modifies bids, pauses campaigns, or adjusts budgets should be tested in read-only mode first - verify the output matches expectations on a single low-spend campaign before enabling write access account-wide.
Spend five minutes on a security review for every tool you build. Then focus on what the tool does and whether it is useful.
