CVE-2015-6785

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 CSPSource::hostMatches function in WebKit/Source/core/frame/csp/CSPSource.cpp in the Content Security Policy (CSP) implementation in Google Chrome before 47.0.2526.73 accepts an x.y hostname as a match for a *.x.y pattern, which might allow remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging a policy that was intended to be specific to subdomains.
