Description Martin Prpič 2015-10-16 08:57:09 EDT

A cross-origin restriction bypass flaw was found in Firefox:

Security researcher Abdulrahman Alqabandi reported that the fetch() API did not correctly implement the Cross-Origin Resource Sharing (CORS) specification, allowing a malicious page to access private data from other origins. Mozilla developer Ben Kelly independently reported the same issue.

This issue was fixed in Firefox 41.0.2.
