Impact

In CI contexts, the IG Publisher CLI uses git commands to determine the URL of the originating repo. If the repo was cloned, or otherwise set to use a repo that uses a username and credential based URL, the entire URL will be included in the built Implementation Guide, exposing username and credential. This does not impact users that clone public repos without credentials, such as those using the auto-ig-build continuous integration infrastructure.

Patches

This problem has been patched in release 1.8.9

Workarounds

Users should update to 1.8.9 or the latest release

OR

Users should ensure the IG repo they are publishing does not have username or credentials included in the origin URL. Running the command git remote origin url should return a URL that contains no username, password, or token.

OR

Users should run the IG Publisher CLI with the -repo parameter and specify a URL that contains no username, password, or token.
