CVE-2015-7187: Mozilla Firefox

Medium severity, CVSS 4.3. EPSS: 1.9% chance of exploitation in the next 30 days.

The Add-on SDK in Mozilla Firefox before 42.0 misinterprets a "script: false" panel setting, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via inline JavaScript code that is executed within a third-party extension.

Affected products

• Mozilla Firefox: up to and including 41.0.2
