CORS requests should not follow 30x redirections after preflight Announced: March 31, 2015 Reporter: Christoph Kerschbaumer, Muneaki Nishimura Impact: High Products: Firefox, Firefox ESR, Thunderbird Fixed in: Firefox 37 Firefox ESR 31.6 Thunderbird 31.6 Description 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.
