Mozilla Firefox before 44.0.2 does not properly restrict the interaction between Service Workers and plugins, which allows remote attackers to bypass the Same Origin Policy via a crafted web site that triggers spoofed responses to requests that use NPAPI, as demonstrated by a request for a crossdomain.xml file.

Exploit prediction (EPSS)

1.50% probability of exploitation in the next 30 days, higher than 74% of all scored CVEs.
