Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
TinyEnv is an environment variable loader for PHP applications. In versions 1.0.1, 1.0.2, 1.0.9, and 1.0.10, TinyEnv did not require the `.env` file to exist when loading environment variables. This could lead to unexpected behavior where the application silently ignores missing configuration, potentially causing insecure defaults or deployment misconfigurations. The issue has been fixed in version 1.0.11. All users should upgrade to 1.0.11 or later. As a workaround, users can manually verify the existence of the `.env` file before initializing TinyEnv.

Recommended fix High confidence

1.0.11 or later

  1. Identify the current TinyEnv version in your project (check composer.json or your package manager)
  2. Update TinyEnv to version 1.0.11 or later using your package manager (e.g., composer update datahihi1/tiny-env or composer require datahihi1/tiny-env:^1.0.11)
  3. After upgrading, verify that your application now properly handles missing .env files and throws an error rather than silently continuing with insecure defaults
  4. As an alternative workaround (if immediate upgrade is not possible), add a check before initializing TinyEnv to verify the .env file exists: use file_exists('.env') before calling TinyEnv initialization
