How to Fix GHSA-6wjw-qf87-fv5v

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

illuminate/encryption fixed: 5.5.40 
Upgrade illuminate/encryption to 5.5.40
illuminate/encryption fixed: 5.6.15 
Upgrade illuminate/encryption to 5.6.15
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 illuminate/encryption

How to Check if You Are Affected

To determine whether your application is affected by GHSA-6wjw-qf87-fv5v, inspect your project dependencies for Illuminate/encryption:

inspect dependencies for illuminate/encryption

Analyze the terminal output to locate any version of Illuminate/encryption in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.5.40), 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-1240: Use of a Cryptographic Primitive with a Risky Implementation, where to fulfill the need for a cryptographic primitive, the product implements a cryptographic algorithm using a non-standard, unproven, or disallowed/non-compliant cryptographic implementation. In Illuminate/encryption, 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

A potential exploit of the Laravel Encrypter component that may cause the Encrypter to fail on decryption and unexpectedly return false. To exploit this, the attacker must be able to modify the encrypted payload before it is decrypted. Depending on the code within your application, this could lead to unexpected behavior when combined with weak type comparisons, for example: ```php <?php $decyptedValue = decrypt($secret); if ($decryptedValue == '') { // Code is run even though decrypted value is false... } ```
