Overview
Affected versions of this package are vulnerable to Command Injection via the processing of crafted project names containing shell metacharacters during the generation of OpenStack RC files. An attacker can access sensitive information or modify data by tricking a highly privileged user into interacting with a maliciously named project. This is only exploitable if the attacker has high privileges and can influence project naming, and if a user interacts with the generated RC file scripts.
