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!');
