How do I fix GHSA-6wjw-qf87-fv5v?

Update illuminate/encryption to 5.5.40 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6wjw-qf87-fv5v is resolved across your whole dependency graph.

How do I detect GHSA-6wjw-qf87-fv5v in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for illuminate/encryption. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-6wjw-qf87-fv5v if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-6wjw-qf87-fv5v?

O3 pinpoints whether GHSA-6wjw-qf87-fv5v is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-6wjw-qf87-fv5v actively exploited in the wild?

No public exploit code has been indexed for GHSA-6wjw-qf87-fv5v yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

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...
}
