CVE-2020-11515: Rankmath Seo

Medium severity, CVSS 6.1. EPSS: 2.1% chance of exploitation in the next 30 days.

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).

Affected products

• Rankmath Seo: up to and including 1.0.40.2
