[-] Vulnerabilities Description: 1) The vulnerability exists because the "EmailsControllerActionGetFromFields::getEmailSignatures()” method is using the unserialize() function with the "account_signatures” user preference, and such a value can be arbitrarily manipulated by evil users through the EmailUIAjax interface. This can be exploited to inject arbitrary PHP objects into the application scope, allowing an attacker to perform a variety of attacks, such as executing arbitrary PHP code. 2) The vulnerability exists because the "EmailsControllerActionGetFromFields::handleActionGetFromFields()” method is using the unserialize() function with the "showFolders” user preference, and such a value can be arbitrarily manipulated by evil users through the EmailUIAjax interface. This can be exploited to inject arbitrary PHP objects into the application scope, allowing an attacker to perform a variety of attacks, such as executing arbitrary PHP code.
