CVE-2020-8595: Improper Authentication

February 12, 2020 (updated February 20, 2020)

The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting a valid JWT token. For example, an attacker can add a ? or # character to a URI that would otherwise satisfy an exact-path match.
