What the vulnerability does
01Description
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.
Explanation of Vulnerability in Simple Terms

An attacker with a low-privilege account can change information without the system verifying their permissions. The vulnerability affects the integrity of stored data but does not expose sensitive information or disrupt site availability.
