Echo: HTTPS Redirect And HSTS Bypass Via Unconditional Trust Of Forwarded Scheme Headers

Description "Context.Scheme" unconditionally trusts four client-controlled HTTP headers to determine the request scheme, with no mechanism to configure trusted sources. This allows a remote unauthenticated attacker to bypass HTTPS redirect enforcement and suppress HSTS headers. The trusted header...

Open Redirect

Overview Affected versions of this package are vulnerable to Open Redirect via the Scheme method in the Context component. An attacker can cause WWWRedirect, NonWWWRedirect, and their WithConfig variants to place an attacker-chosen URI scheme in the Location header by sending a request with a...
