Description msiddiqu 2020-07-27 10:34:55 UTC 
A user controlling the username mount option can embed shell commands that will be run in the context of the calling user.
Comment 3 Cedric Buissart 2020-09-07 06:43:21 UTC 
Statement:

In order to exploit this flaw, the attacker would need to be able to inject a specially crafted username into the command run by root. This requires a specific setup (e.g.: sudo rules, etc.).
As a result, the vulnerability is considered as low severity.
