Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.81%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In codecov (npm package) before version 3.7.1 the upload method has a command injection vulnerability. Clients of the codecov-node library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability. A similar CVE (CVE-2020-7597 for GHSA-5q88-cjfq-g2mh) was issued but the fix was incomplete. It only blocked &, and command injection is still possible using backticks instead to bypass the sanitizer. The attack surface is low in this case. Particularly in the standard use of codecov, where the module is used directly in a build pipeline, not built against as a library in another application that may supply malicious input and perform command injection.
