GMS-2016-44: DOM-based XSS

July 21, 2016

Three functions exposed by the Gmail.js API (not the Google Gmail API) are vulnerable to DOM-based cross site scripting. The three functions are tools.parse_response, helper.get.visible_emails_post, and helper.get.email_data_post. Each one of these functions calls new Function() with user data passed as the argument.
