How to Fix CVE-2019-10800

To remediate this vulnerability, upgrade all affected Codecov dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

codecov fixed: 2.0.16 
pip install codecov>=2.0.16
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show codecov

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-10800, inspect your installed packages using pip:

pip show codecov

Analyze the terminal output to locate any version of Codecov in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.16), your application is affected.

Note: The pip show codecov command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In Codecov, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This affects the package codecov before 2.0.16. The vulnerability occurs due to not sanitizing gcov arguments before being being provided to the popen method.
