CVE-2026-100158SQL Chart Builder <= 3.0.6 - Authenticated (Subscriber+) Stored Cross-Site Scripting via SQL Chart Label (X-axis) via Stored User Field
Medium 6.4
In plain English
A medium-severity cross-site scripting in SQL Chart Builder from elvinhaci. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 9% of all known vulnerabilities).
Official description
The SQL Chart Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-axis column value ($value->$xarg_s from $wpdb->get_results())' parameter in all versions up to, and including, 3.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have published a chart whose SQL query returns a column controllable by a lower-privileged user, such as wp_users.display_name, which a Subscriber can populate with a payload via the standard WordPress profile page at /wp-admin/profile.php.
