Summary

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. This allows unauthenticated attackers to update the plugin's settings, including the Klubraum API token and introduction text, effectively hijacking the plugin's integration with the Klubraum service.

Risk Assessment

An attacker can hijack the integration with Klubraum, potentially leading to data theft or unauthorized actions on behalf of the site.

Recommendation

Update the Klubraum Membership Request plugin to the latest version that includes the capability check fix. If unavailable, temporarily disable the plugin.
