High impact if exploited, but EPSS currently rates exploitation as unlikely (3.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The extlib gem 0.9.15 and earlier for Ruby does not properly restrict casts of string values, which might allow remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.
