- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- sminozzi Memory Usage, Memory Limit, PHP and Server Memory Health Check and Provide Suggestions: through 3.98

## Description

The Memory Usage plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.98. This is due to missing nonce validation in the wpmemory_install_plugin() function. This makes it possible for unauthenticated attackers to silently install one of the several whitelisted plugins via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
