CVE-2016-7954
Bundler 1.x might allow remote attackers to inject arbitrary Ruby code into an application by leveraging a gem name collision on a secondary source.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.82%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
