Name of the Vulnerable Software and Affected Versions willitmerge versions 0.2.1 and prior

Description willitmerge is a command line tool used to check if pull requests are mergeable. A command injection issue exists in versions 0.2.1 and earlier due to the use of an insecure child process execution API (

exec

) that concatenates user-controlled input. This allows for arbitrary command execution. The input can be provided through command-line flags or within the target repository. At the time of publication, a fix is not publicly available.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
