Description Huzaifa S. Sidhpurwala 2012-03-14 01:51:33 UTC 
Security Researcher Mike Brooks of Sitewatch reported that if multiple Content Security Policy (CSP) headers are present on a page, they have an additive effect page policy. Using carriage return line feed (CRLF) injection, a new CSP rule can be introduced which allows for cross-site scripting (XSS) on sites with a separate header injection vulnerability.
