CVE-2026-4126
At a glance
CVE-2026-4126 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Table Manager WordPress plugin, affecting versions <= 1.0.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.0.1; sites on affected versions should update now. Disclosed April 2026, reported by Itthidej Aramsri (Boeing777).
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Table Manager <= 1.0.0 carries this weakness at table_manager, and reaching it takes an account at Contributor level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.
The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Table Manager the fix is 1.0.1: builds <= 1.0.0 are affected, anything from 1.0.1 onward is not.
Remediation
Update to version 1.0.1, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: Table Manager 1.0.1 closes this, and updating the plugin is the step that ends it.
