Executive Summary

This vulnerability affects the WP Recipe Maker WordPress plugin versions 9.8.0 through 10.8.1. It involves a missing authorization check in a REST route, allowing unauthenticated users to write unlimited data into any user's metadata. This can permanently disrupt the affected account, including administrators, by preventing it from loading.

Detection Guidance

Check the installed version of the WP Recipe Maker plugin. If it is between 9.8.0 and 10.8.1, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin files for version details.

Impact Analysis

An attacker could exploit this to corrupt or disable your WordPress account, including admin accounts, by filling metadata with excessive data. This could prevent you from accessing your site or performing administrative tasks.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by allowing unauthorized data modification in user metadata. Unrestricted write access to metadata may violate data integrity and access control requirements under these regulations.

Mitigation Strategies

Update the WP Recipe Maker plugin to version 10.8.2 or later immediately. Disable the plugin temporarily if an update is not immediately possible, but note this may affect site functionality.
