What the vulnerability does

01Description

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.

Explanation of Vulnerability in Simple Terms

02Summary

Table Manager versions 1.0.0 and earlier expose sensitive information to authenticated users. A logged-in user can read data they should not have access to due to insufficient access controls. The exposure is limited to confidentiality; the vulnerability does not allow modification or deletion of data. Update to a version newer than 1.0.0.
