CyberRota Analysis

AI-Generated

The vulnerability allows unauthenticated users to directly send POST requests to update employee records, bypassing necessary ownership checks due to inadequate HMAC validation in the update action. This flaw can lead to unauthorized modifications of sensitive employee data. Organizations using the affected extension should prioritize remediation to prevent potential data integrity issues and unauthorized access.

Original NVD Description

The extension validates the HMAC of a frontend employee edit link only in the action that renders the edit form, not in the action that persists the change. An unauthenticated visitor who knows the UID of a visible employee record can send a direct POST request to the update action and overwrite that record without a valid edit link or any ownership check.
