FKIE_CVE-2026-4126

Vulnerability from fkie_nvd - Published: 2026-04-22 09:16 - Updated: 2026-06-17 10:56
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
Summary
The Table Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.0.0 via the 'table_manager' shortcode. The shortcode handler `tablemanager_render_table_shortcode()` takes a user-controlled `table` attribute, applies only `sanitize_key()` for sanitization, and concatenates the value with `$wpdb->prefix` to form a full database table name. It then executes `DESC` and `SELECT *` queries against this table and renders all rows and columns to the frontend. There is no allowlist check to ensure only plugin-created tables can be accessed — the `tablemanager_created_tables` option is only referenced in admin functions, never in the shortcode handler. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data from arbitrary WordPress database tables.
