Unauthenticated SQL Injection in JS Help Desk <= 3.0.9 versions.

AnalysisAI

SQL injection in the JS Help Desk WordPress plugin versions 3.0.9 and earlier allows remote unauthenticated attackers to inject arbitrary SQL into backend database queries. The flaw was disclosed via Patchstack and carries a CVSS 9.3 with scope change, meaning successful exploitation can read database contents beyond the plugin's own data. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Technical ContextAI

JS Help Desk (vendor 'ahmad', CPE cpe:2.3:a:ahmad:js_help_desk) is a WordPress support-ticket plugin that exposes ticket submission and lookup endpoints to unauthenticated visitors. CWE-89 indicates user-supplied input is concatenated into SQL statements without parameterization or proper escaping, so crafted request parameters reach the WordPress wpdb query layer directly. Because WordPress plugins share the same database schema (wp_users, wp_options) as the host site, a scope-changed SQLi in any plugin can read core CMS tables including password hashes and session/auth secrets.

RemediationAI

Patch status is ambiguous from the provided data - the Patchstack reference describes the vulnerability as affecting '<= 3.0.9' which implies a fixed release exists, but no exact fix version is included in the input, so treat this as 'Patch availability per vendor advisory; exact fixed version not independently confirmed from input data' and consult the Patchstack page directly at https://patchstack.com/database/wordpress/plugin/js-support-ticket/vulnerability/wordpress-js-help-desk-plugin-3-0-9-sql-injection-vulnerability for the upgraded version number before deploying. Until the upgrade is verified and applied, deactivate the JS Help Desk plugin from wp-admin (trade-off: support-ticket intake stops, existing tickets become inaccessible to staff), or front the site with a WAF ruleset blocking SQL meta-characters on the plugin's AJAX/REST endpoints (trade-off: false positives on legitimate ticket bodies containing quotes or SQL keywords). Restricting wp-admin/admin-ajax.php and the plugin's REST routes to authenticated sessions via an .htaccess or nginx allowlist is not a viable mitigation here because the flaw is reachable without authentication on public ticket-submission paths.
