GHSA-xp63-6vf5-xf3v
Command injection in codecov (npm package)
Quick fix
GHSA-xp63-6vf5-xf3v — codecov: upgrade to the fixed version with the command below.
npm install codecov@3.7.1Details
### Impact
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 was issued: [CVE-2020-7597](https://github.com/advisories/GHSA-5q88-cjfq-g2mh), but the fix was incomplete. It only blocked `&`, and command injection is still possible using backticks instead to bypass the sanitizer.
We have written a [CodeQL](https://codeql.com) query, which automatically detects this vulnerability. You can see the results of the query on the `codecov-node` project [here](https://lgtm.com/query/7714424068617023832/).
### Patches This has been patched in version 3.7.1
### Workarounds
None, however, 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.
