Description
The HAPPY – Helpdesk Support Ticket System plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the 'submit_form_reply' AJAX action in all versions up to, and including, 1.0.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to submit replies to arbitrary support tickets by manipulating the 'happy_topic_id' parameter, regardless of whether they are the ticket owner or have been assigned to the ticket.

AI Analysis

Impact

The plugin contains a missing capability check on the ‘submit_form_reply’ AJAX action, which is a classic missing authorization flaw (CWE‑862). The flaw allows any authenticated WordPress user with Subscriber level or higher to alter any support ticket by manipulating the ‘happy_topic_id’ parameter, even if they are not the ticket owner or have not been assigned to the ticket. This can be used to inject unwanted or misleading content into tickets, effectively compromising the integrity of the support system.

Affected Systems

This weakness exists in the villatheme HAPPY – Helpdesk Support Ticket System plugin for WordPress in all releases up to and including 1.0.9.

Risk and Exploitability

The CVSS score of 4.3 indicates a moderate level of severity, while the EPSS score of less than 1% suggests a low probability of exploitation at present. The vulnerability is not listed in the CISA KEV catalog. Once an attacker is authenticated with Subscriber or higher privileges, they can abuse the flaw by sending a crafted AJAX request to the reply endpoint, requiring no additional conditions.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the HAPPY – Helpdesk Support Ticket System plugin to any version newer than 1.0.9, which corrects the missing capability check on the reply action.
  • If an upgrade is not immediately possible, limit the ability to reply to tickets by assigning a custom capability that only administrators or dedicated support staff possess, and modify the plugin to enforce that capability before processing reply submissions.
  • As a temporary protection, suppress the ‘submit_form_reply’ AJAX action for roles below administrator by adding a filter or custom code that blocks the request until the official patch is available.
