    "summary": "### Summary `gix-path` executes `git` to find the path of a configuration file that belongs to the `git` installation itself, but mistakenly treats the local repository's configuration as system-wide if no higher scoped configuration is found. In rare cases, this causes a less trusted repository to be treated as more trusted, or leaks sensitive information from one repository to another, such as sending credentials to another repository's remote. ### Details In `gix_path::env`, the underlying implementation of the `installation_config` and `installation_config_prefix` functions calls `git config -l --show-origin` and parses the first line of the output to extract the path to the configuration file holding the configuration variable of highest [scope](https://git-scm.com/docs/git-config#SCOPES): While the configuration variable of highest scope is not usually in the local scope, there are practical situations where this occurs: - A configuration file truly associated with the installation is not present on all systems and can occasionally be empty. Likewise, there may be no variables in the global scope. - Configuration files associated with those higher scopes may be deliberately skipped by setting the `GIT_CONFIG_SYSTEM` and `GIT_CONFIG_GLOBAL` environment variables to `/dev/null` (or to `NUL` on Windows). This prevents `gix-path` from finding the path of configuration files for those scopes, while not preventing downstream components such as the function in `gix-config` fro",
