Executive Summary

This vulnerability affects the UpdraftPlus WordPress plugin. It allows any authenticated user, including low-privilege users like subscribers, to access sensitive remote storage credentials such as passwords and secret keys. This occurs because the plugin fails to check user capabilities when displaying these settings in a post-migration state.

Detection Guidance

Check the installed version of the UpdraftPlus plugin in WordPress. If it is between 1.23.8 and 1.26.7, the system is vulnerable. Use commands like 'wp plugin list' in WP-CLI or inspect the plugin files in /wp-content/plugins/updraftplus/

Impact Analysis

An attacker could exploit this to steal backup destination credentials, potentially gaining access to stored backups or other sensitive data. This could lead to unauthorized data access, data breaches, or further compromise of the WordPress site.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations may face compliance penalties and reputational damage if exploited.

Mitigation Strategies

Update the UpdraftPlus plugin to version 1.26.8 or later immediately. Remove or disable the plugin if updating is not possible. Rotate any exposed credentials for remote storage services.
