CVE-2014-8638
|
| Summary | Security researcher Muneaki Nishimura reported that navigator.sendBeacon() does not follow the cross-origin resource sharing (CORS) specification. This results in the request from sendBeacon() lacking an origin header in violation of the W3C Beacon specification and not being treated as a CORS request. This allows for a potential Cross-site request forgery (XSRF) attack from malicious websites. In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts. |
