All the vulnerabilities related to the version 3.6.3 of the package
codecov NPM module allows remote attackers to execute arbitrary commands
codecov-node npm module before 3.6.5 allows remote attackers to execute arbitrary commands.The value provided as part of the gcov-root argument is executed by the exec function within lib/codecov.js. This vulnerability exists due to an incomplete fix of CVE-2020-7596.
Command injection in codecov (npm package)
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, 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 query, which automatically detects this vulnerability. You can see the results of the query on the codecov-node project here.
This has been patched in version 3.7.1
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.
If you have any questions or comments about this advisory:
Inefficient Regular Expression Complexity in validator.js
validator.js prior to 13.7.0 is vulnerable to Inefficient Regular Expression Complexity
Inefficient Regular Expression Complexity in Validator.js
Versions of validator prior to 13.7.0 are affected by an inefficient Regular Expression complexity when using the rtrim and trim sanitizers.
The problem has been patched in validator 13.7.0
