TinyEnv Environment Variable Loader for PHP Inline Comment Handling Vulnerability

A vulnerability exists in TinyEnv, a PHP environment variable loader, in versions 1.0.9 and 1.0.10. The issue arises because the software failed to properly remove inline comments from .env file values. This flaw could result in misconfigurations or unexpected behavior, as environment variables might include unintended characters or comment text. Applications that rely on precise environment values could encounter logic errors, insecure defaults, or authentication failures.

Impact

The vulnerability could lead to misconfigured environment variables, allowing applications to behave unexpectedly. This may result in logic errors, insecure default settings, or authentication issues.

Remediation

The vulnerability has been fixed in TinyEnv version 1.0.11. Users are advised to upgrade to this version. As a temporary measure, avoid using inline comments in .env files or manually sanitize the loaded values.
