Re: RemoteUser authn servlet uses hardcoded checkHeaders ( https://shibboleth.atlassian.net/browse/IDP-2084?atlOrigin=eyJpIjoiNDAwMTdiM2UyYjQxNDE5NGFlMGE5MjQzM2VlMThlZGEiLCJwIjoiaiJ9 )

This isn’t a terribly likely expsoure for a few reasons. You’d have to not populate REMOTE_USER itself (or not be relying on it), and you’d have to have no servlet attributes specified to use, and then finally it would rely on a header, at which point (as you did) it would presumably be obvious while testing that it wasn’t working.

It doesn’t allow for any other header to work, so at that point I can’t imagine how it would have been deployed.

So worth an advisory but not critical.
