Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (6.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In ruamel.yaml through 0.16.7, the load method allows remote code execution if the application calls this method with an untrusted argument. In other words, this issue affects developers who are unaware of the need to use methods such as safe_load in these use cases.
