Description Huzaifa S. Sidhpurwala 2012-06-03 08:34:52 UTC

Security researcher Adam Barth found that inline event handlers, such as onclick, were no longer blocked by Content Security Policy's (CSP) inline-script blocking feature. Web applications relying on this feature of CSP to protect against cross-site scripting (XSS) were not fully protected.
