Payload invalid, DecryptException thrown

[sheriffmarley]

Bug report

What I did:

I tried to access a log file (laravel-2019-05-19.log)

What I expected to happen:

Show the logfile

What happened:

A DecryptException was thrown The payload is invalid. {"userId":1,"exception":"[object] (Illuminate\\Contracts\\Encryption\\DecryptException(code: 0): The payload is invalid. at /var/www/html/main/vendor/laravel/framework/src/Illuminate/Encryption/Encrypter.php:195)

What I've already tried to fix it:

Since the filename seems to be only a base64 encoded string, I replaced decrypt($file_name) with base64_decode($file_name) and it worked.

Hi @sheriffmarley ,

Yes, we've indeed changed the filename encryption from base64 to Laravel's default - we believe that's better security. With encrypt()/decrypt() people can't base64encode a filename they want, and pass it to the URL. Not even admins, which we usually trust.

You can see in my link above that the changes have been both in the LogController, and in the blade files. I suspect you've run composer update, so have the latest controller, but have the old blade file, by having published it to your resources/views/vendor/backpack/logmanager/logs.blade.php. If your blade file uses base64 instead of encrypt/decrypt, take a look at the changes we've made in the link above (they're super simple) and do them to your blade file too.

Cheers!
