CVE-2026-101325 Details
Description
The Newsletters plugin for WordPress is vulnerable to time-based SQL Injection via the 'id' parameter in all versions up to, and including, 4.18.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. An attacker can obtain the required nonce and subscriberauth cookie without a WordPress account by simply subscribing through the public newsletter form and opening the management link sent via email; the ownership check verifies only the subscriber_id field and does not validate that the injected id parameter belongs to the authenticated subscriber.
A time-based SQL injection vulnerability has been identified in the Newsletters plugin for WordPress, affecting all versions through 4.18.1. The issue arises from inadequate escaping of user-supplied data in the 'id' parameter, allowing authenticated attackers with subscriber-level access or higher to inject additional SQL queries. This exploitation could lead to unauthorized access to sensitive database information. Notably, an attacker can acquire the necessary nonce and subscriberauth cookie by subscribing through the public newsletter form and accessing the management link sent via email, as the ownership check only verifies the subscriber_id without confirming the injected id's validity.
Users are advised to update the Newsletters plugin to version 4.18.2 or a newer patched version.
