CVE-2019-11695: Mozilla Firefox

Medium severity, CVSS 4.3. EPSS: 0.7% chance of exploitation in the next 30 days.

A custom cursor defined by scripting on a site can position itself over the addressbar to spoof the actual cursor when it should not be allowed outside of the primary web content area. This could be used by a malicious site to trick users into clicking on permission prompts, doorhanger notifications, or other buttons inadvertently if the location is spoofed over the user interface. This vulnerability affects Firefox < 67.

Affected products

• Mozilla Firefox: before 67.0 (fixed in 67.0)
