GHSA-3j7m-5g4q-gfpc: TinyEnv: Missing .env file not required — may cause unexpected behavior

Impact

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.

Affected versions:

1.0.1 → 1.0.2
1.0.9 → 1.0.10

Patches

The issue has been fixed in version 1.0.11.
All users should upgrade to 1.0.11 or later.

Workarounds

As a workaround, users can manually verify the existence of the .env file before initializing TinyEnv, for example:

if (!file_exists(__DIR__ . '/.env')) {
    throw new RuntimeException('.env file is missing!');
}
