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...
}

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for illuminate/encryption, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    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.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-6wjw-qf87-fv5v can be triaged on real exposure rather than presence alone.

Tailored to GHSA-6wjw-qf87-fv5v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
