Summary
Laravel Encrypter Failure to decryption vulnerability
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
$decyptedValue = decrypt($secret);
if ($decryptedValue == '') {
// Code is run even though decrypted value is false...
}
Impact

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-6WJW-QF87-FV5V? GHSA-6WJW-QF87-FV5V is a low-severity security vulnerability in illuminate/encryption (composer), affecting versions >= 5.5.0, < 5.5.40. It is fixed in 5.5.40, 5.6.15.
- Which versions of illuminate/encryption are affected by GHSA-6WJW-QF87-FV5V? illuminate/encryption (composer) versions >= 5.5.0, < 5.5.40 is affected.
- Is there a fix for GHSA-6WJW-QF87-FV5V? Yes. GHSA-6WJW-QF87-FV5V is fixed in 5.5.40, 5.6.15. Upgrade to this version or later.
- Is GHSA-6WJW-QF87-FV5V exploitable, and should I be worried? Whether GHSA-6WJW-QF87-FV5V is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-6WJW-QF87-FV5V is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
