sharp is an application for Node.js image processing. Prior to version 0.30.5, there is a possible vulnerability in logic that is run only at npm install
time when installing versions of sharp
prior to the latest v0.30.5. If an attacker has the ability to set the value of the PKG_CONFIG_PATH
environment variable in a build environment then they might be able to use this to inject an arbitrary command at npm install
time. This is not part of any runtime code, does not affect Windows users at all, and is unlikely to affect anyone that already cares about the security of their build environment. This problem is fixed in version 0.30.5.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

Command injection vulnerabilities typically occur when:
Many protocols and products have their own custom command language. While OS or shell command strings are frequently discovered and targeted, developers may not realize that these other command languages might also be vulnerable to attacks. Command injection is a common problem with wrapper programs.
