CVE-2026-9848: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in emarket-design Customer Support Ticket System & Helpdesk
The WP Ticket plugin for WordPress is vulnerable to SQL Injection via the WordPress search query parameter (`s`) in versions up to, and including, 6.0.4 The plugin hooks WordPress's `posts_request` filter with `wp_ticket_com_posts_request()`, which calls `emd_author_search_results()` when the current request is an unauthenticated front-end search. That function reads `$query->query_vars['s']` — already wp_unslash()'d by `WP_Query::parse_query()`, so wp_magic_quotes protection has been stripped — and concatenates the raw value into a SQL `LIKE` clause inside a UNION sub-SELECT appended to the main query, with no `$wpdb->prepare()` or escaping. This makes it possible for unauthenticated attackers to append additional SQL queries into already-existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2026-9848 describes an SQL Injection vulnerability in the WP Ticket plugin for WordPress (emarket-design Customer Support Ticket System & Helpdesk). The vulnerability occurs because the plugin uses the WordPress 'posts_request' filter with the function 'wp_ticket_com_posts_request()', which calls 'emd_author_search_results()' during unauthenticated front-end searches. This function reads the search query parameter 's' after wp_unslash() processing but without any further escaping or use of $wpdb->prepare(), concatenating the raw input directly into a SQL LIKE clause inside a UNION sub-SELECT appended to the main query. This improper neutralization of special SQL elements (CWE-89) allows unauthenticated attackers to append additional SQL queries, potentially extracting sensitive information from the database. The CVSS 3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high impact on confidentiality with no impact on integrity or availability. No patch or official remediation has been disclosed as of the publication date.
Potential Impact
An unauthenticated attacker can exploit this SQL Injection vulnerability to extract sensitive information from the backend database of the WP Ticket plugin. The vulnerability impacts confidentiality (high impact) but does not affect integrity or availability. Because the injection occurs in a front-end search parameter, it can be triggered remotely without authentication, increasing the risk of data exposure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling the affected search functionality or restricting access to it to trusted users only. Monitoring for unusual database queries and applying web application firewall (WAF) rules that detect SQL injection attempts may provide temporary protection.
