Description Huzaifa S. Sidhpurwala 2015-03-30 08:09:54 UTC
Mozilla developer Christoph Kerschbaumer discovered an issue while investigating Mozilla Foundation Security Advisory 2015-03, previously reported by security researcher Muneaki Nishimura. This flaw was that a cross-origin resource sharing (CORS) request should not follow 30x redirections after preflight according to the specification. This only affects sendBeacon() requests but could allow 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.
