Description Huzaifa S. Sidhpurwala 2012-07-14 12:34:27 UTC 
Security researcher Karthikeyan Bhargavan of Prosecco at INRIA reported Content Security Policy (CSP) 1.0 implementation errors. CSP violation reports generated by Firefox and sent to the "report-uri" location include sensitive data within the "blocked-uri" parameter. These include fragment components and query strings even if the "blocked-uri" parameter has a different origin than the protected resource. This can be used to retrieve a user's OAuth 2.0 access tokens and OpenID credentials by malicious sites.
