Summary

The App Builder WordPress plugin is affected from 3.8.4 before 5.7.1. Missing authorization (CWE-862) lets unauthenticated visitors write attacker-supplied data to one of its options. A separate unauthenticated request then redirects the visitor's browser to a URI built from that stored data. A remote attacker needs no account or user interaction, and a public exploit is linked in the references.

Description from the CNA

The App Builder WordPress plugin before 5.7.1 does not require authentication or authorisation before writing attacker-supplied data to one of its options and, on a separate unauthenticated request, redirecting the visitor's browser to a URI built from that stored data.
