CVE-2020-11515: WordPress plugin vulnerability

Share this with people that should know this:

The Rank Math plugin through 1.0.40.2 for WordPress allows unauthenticated remote attackers to create new URIs (that redirect to an external web site) via the unsecured rankmath/v1/updateRedirection REST API endpoint. In other words, this is not an “Open Redirect” issue; instead, it allows the attacker to create a new URI with an arbitrary name (e.g., the /exampleredirect URI).
