The JoomSport - for Sports: Team & League, Football, Hockey & more plugin for WordPress is vulnerable to time-based SQL Injection via 'event' Shortcode Attribute in all versions up to, and including, 5.7.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The shortcode can be embedded in posts or pages by Contributor-level users, making this exploitable by any authenticated user with at least that role.
AnalysisAI
Time-based SQL injection in the JoomSport WordPress plugin (all versions through 5.7.9) enables authenticated contributors to exfiltrate sensitive database contents via unsanitized 'event' shortcode attributes. The flaw exists in at least two code paths - joomsport-shortcodes.php and class-jsport-getplayers.php - where user-supplied shortcode parameters are interpolated into SQL queries without parameterization or adequate escaping. Because WordPress Contributor-level users can embed shortcodes in posts and pages, the effective attacker pool includes any registered user granted that role, broadening realistic exposure beyond typical authenticated-only flaws. No public exploit code or CISA KEV listing identified at time of analysis, but a patch commit (changeset 3594276) is referenced in the plugin repository.
Technical ContextAI
This is a CWE-89 (SQL Injection) vulnerability rooted in the failure to use parameterized queries or prepared statements in the JoomSport plugin's shortcode processing layer. The WordPress shortcode system allows authors with Contributor access and above to embed arbitrary shortcodes - including JoomSport's 'event' shortcode - directly into post or page content. When WordPress renders that content, the plugin's PHP code constructs SQL queries incorporating the unsanitized 'event' attribute value. The vulnerable logic is confirmed in two files in the 5.7.9 release: includes/joomsport-shortcodes.php at line 299 and sportleague/base/wordpress/classes/class-jsport-getplayers.php at line 102. The exploitation method is time-based (blind) SQL injection, meaning the attacker infers database content by measuring server response delays rather than receiving direct error output, consistent with a scenario where error-based output is suppressed.
RemediationAI
A patch is available: the plugin's SVN changeset 3594276 (https://plugins.trac.wordpress.org/changeset?reponame=&old=3594276%40joomsport-sports-league-results-management&new=3594276%40joomsport-sports-league-results-management) reflects the upstream fix, though the exact patched release version number is not independently confirmed from the available data - administrators should update to the latest available version from the WordPress plugin repository and verify the installed version exceeds 5.7.9. If immediate update is not possible, the most effective compensating control is to restrict Contributor-level user registrations or audit and reduce the contributor user list, as this eliminates the attacker's required foothold entirely. A Web Application Firewall rule blocking time-based SQL injection patterns (e.g., SLEEP(), BENCHMARK(), WAITFOR DELAY) in shortcode attribute values can reduce exploitation success, though WAF bypass remains possible. Disabling the JoomSport plugin entirely removes the attack surface at the cost of all plugin functionality. Restricting post/page creation to Editor-level and above prevents Contributor-level shortcode embedding.
