CVE-2018-10193
LogMeIn LastPass through 4.15.0 allows remote attackers to cause a denial of service (browser hang) via an HTML document because the resource consumption of onloadwff.js grows with the number of INPUT elements.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
