CVE-2015-7215

MEDIUM
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The importScripts function in the Web Workers API implementation in Mozilla Firefox before 43.0 allows remote attackers to bypass the Same Origin Policy by triggering use of the no-cors mode in the fetch API to attempt resource access that throws an exception, leading to information disclosure after a rethrow.
