Advisories for Npm/Blamer package

Versions of the package blamer before 1.0.4 is vulnerable to Arbitrary Argument Injection via the blameByFile() API. The library does not sanitize for user input or validate the given file path conforms to a specific schema, nor does it properly pass command-line flags to the git binary using the double-dash POSIX characters (–) to communicate the end of options.

Code injection vulnerability in blamer may result in remote code execution when the input can be controlled by an attacker.

Blamer versions allows execution of arbitrary commands. It is possible to inject arbitrary commands as part of the arguments provided to blamer.
