Description Huzaifa S. Sidhpurwala 2013-08-06 09:24:27 UTC 
Mozilla community member Federico Lanusse reported a mechanism where a web worker can violate same-origin policy and bypass cross-origin checks through XMLHttpRequest. This could allow for cross-site scripting (XSS) attacks by web workers.

In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
