Executive Summary

The GTranslate WordPress plugin before version 5.0.1 fails to remove shortcodes from outgoing email content before processing them. This allows unauthenticated users to execute server-side shortcodes if they are registered on the site in a non-default configuration.

Detection Guidance

Check if the GTranslate WordPress plugin version is below 5.0.1 by inspecting the plugin files or WordPress admin panel. Look for unauthorized shortcode execution in email content or server logs.

Impact Analysis

An attacker could exploit this to execute arbitrary server-side code via email translation, potentially leading to unauthorized actions, data access, or site compromise depending on registered shortcodes.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating confidentiality requirements in GDPR and HIPAA. Compliance may be compromised if sensitive data is exposed or altered.

Mitigation Strategies

Update the GTranslate plugin to version 5.0.1 or later immediately. If updating is not possible, consider disabling the plugin or removing email translation features until patched.
