How to Fix CVE-2025-58758

To remediate this vulnerability, upgrade all affected TinyEnv dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

datahihi1/tiny-env fixed: 1.0.3 
Upgrade datahihi1/tiny-env to 1.0.3
datahihi1/tiny-env fixed: 1.0.11 
Upgrade datahihi1/tiny-env to 1.0.11
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for datahihi1/tiny-env

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-58758, inspect your project dependencies for TinyEnv:

inspect dependencies for datahihi1/tiny-env

Analyze the terminal output to locate any version of TinyEnv in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-703: Improper Check or Handling of Exceptional Conditions, where the product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product. In TinyEnv, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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