OSV carries this publisher advisory for illuminate/encryption, illuminate/encryption. This is an aggregated source copy; consult the original publisher and compare update dates.

01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
illuminate/encryption
source listedECOSYSTEM: introduced 5.5.0; fixed 5.5.40
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... } ```
illuminate/encryption
source listedECOSYSTEM: introduced 5.6.0; fixed 5.6.15
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... } ```

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
