CVE-2016-0752: Possible Information Leak Vulnerability

February 15, 2016 (updated August 8, 2019)

Applications that pass unverified user input to the render method in a controller may be vulnerable to an information leak vulnerability. Carefully crafted requests can render files from unexpected places like outside the application’s view directory, and can possibly escalate this to a remote code execution attack.
