Appending any string to the Portal Sharing Directory's Self resource URL generates the Portal Self resource, instead of returning the Error 404 error message as it should.

Workaround

Appending new information to the URLs does not alter the results of the Portal page.

This bug negatively affects and clogs security scans on the organization's portals.

Placing the Error 404 error message on the URLs rectifies the issues.
