CVE-2018-20056
There is a stack-based buffer overflow allowing remote attackers to execute arbitrary code without authentication via the goform/formLanguageChange currTime parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
