.env.example Real Values Check — Are Placeholders Actually Placeholders?

DevMeth checks the 48 known AI-code failure patternsnot a penetration test or a security guarantee.

What the issue is

An example or template env file that ships real keys instead of placeholders leaks credentials to everyone who clones or copies the repo as a starting point.

Why AI tools generate it

AI tools sometimes copy the working .env into .env.example so the template runs, filling it with real rather than placeholder values.

How DevMeth detects it

A code scan checks example/sample/template env files for secret-shaped strings and flags them when values are real rather than placeholders.

FAQ

Why is .env.example with real keys a problem?

Example files are meant to be cloned by anyone, so real keys there are broadcast to every consumer of the repo.

What does the scan look for?

Secret-shaped values in example or template env files — the scan flags them when they look real rather than like placeholders.

What is the fix?

Replace all values in example env files with obvious placeholders and rotate any credential that was exposed.
