A data-driven system for fast response to security vulnerability, in one example embodiment, comprises a request detector, a content type evaluator, and a presentation module. A request detector may be configured to detect a request to display content. A content type evaluator may be configured to determine a type of the requested content. A presentation module may be configured to selectively display the requested content based on the determined type of the requested content. The content type evaluator and the presentation module may utilize a data file that stores information related to potential vulnerabilities associated with a content viewing application. Example data file may be an XML file.
