Executive Summary

This vulnerability in the Tutor LMS WordPress plugin allows authenticated users with subscriber level access or higher to modify or delete coupon data without proper authorization. This happens because the plugin's 'bulk_action_handler' and 'coupon_permanent_delete' functions lack adequate capability checks, enabling unauthorized deletion, activation, deactivation, or trashing of coupons. [2]

Impact Analysis

The vulnerability can lead to unauthorized modification or deletion of coupon data in the Tutor LMS plugin. Attackers with low-level authenticated access can delete or alter coupons, potentially causing financial loss, disruption of promotional campaigns, or damage to business operations relying on coupon functionality.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Tutor LMS plugin to version 3.9.4 or later, which includes improved capability checks in the 'bulk_action_handler' function and nonce verification to prevent unauthorized coupon modifications. This update replaces the previous direct capability check with a more robust permission verification method and adds CSRF protection, effectively addressing the vulnerability. [2]
