Mautic 2.15.2 contained sanitization of unserialize PHP functions. Even though the one case where the classes are being unserialized contained exception and enabled the Swift_Message class it was not enough as once the unserialized object got a method call it threw the error message.

This error happened in following cases:

  • PHP 7+
  • Email queue enabled in Mautic configuration.
  • The app/spool/default dir contains some email file that has extension of .finalretry or .sending
    or .tryagain. If it contained only email files with the .message extension it worked correctly.

Steps to reproduce the bug:

  1. Ensure all the requirements are fulfilled to reproduce this error.
  2. To simulate the error send an email, rename the email file extension from .message to .tryagain.
  3. Execute the $ app/console mautic:emails:send command.

You should get this error:

  Error: Swift_Mime_SimpleMimeEntity::_getHeaderFieldModel(): The script tried to execute a method or access a property of an incomplete ob  
  ject. Please ensure that the class definition "Swift_Mime_SimpleHeaderSet" of the object you are trying to operate on was loaded _before_  
   unserialize() gets called or provide an autoloader to load the class definition  

Steps to test this PR:

  1. Run the command again.
  2. The email is send without any error.

@Woeler I didn't notice but we had the same fix in production for a while (since the last security fixes) and it is working perfectly.
