Authorization Bypass in JoomSport WordPress Plugin

Publication date: 2026-07-02

Last updated on: 2026-07-02

Assigner: Wordfence

Description
The JoomSport – for Sports: Team & League, Football, Hockey & more plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.7.8. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to create arbitrary season groups or modify existing group names, participants, and round-type options. Exploitation requires obtaining the joomsportajaxnonce, which is exposed on frontend pages that render a JoomSport shortcode.

Executive Summary

The JoomSport plugin for WordPress has an authorization bypass vulnerability in all versions up to and including 5.7.8. This means the plugin does not properly check if a user is allowed to perform certain actions.

As a result, authenticated users with subscriber-level access or higher can create or modify season groups, group names, participants, and round-type options without proper permission.

Exploitation requires obtaining a specific token called joomsportajaxnonce, which is exposed on frontend pages that display a JoomSport shortcode.

Impact Analysis

This vulnerability allows attackers with low-level authenticated access to manipulate data within the JoomSport plugin.

  • They can create arbitrary season groups.
  • They can modify existing group names.
  • They can change participants and round-type options.

Such unauthorized modifications could lead to data integrity issues and potentially disrupt the intended functionality of sports team and league management on the affected WordPress site.
