Vulnerability Title
Klubraum Membership Request <= 1.1.0 - Missing Authorization to Unauthenticated Arbitrary Plugin Settings Update
Source: CVE Program / CVE List V5
Vulnerability Description
The Klubraum Membership Request plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `kr_mr_store_settings()` function in all versions up to, and including, 1.1.0.
