CVE-2026-17509: WPML Multilingual CMS lets logged-in users steal data
CVE-2026-17509 · published 1 month ago
Summary
The WPML Multilingual CMS plugin for WordPress up to version 4.9.5 allows anyone with a login (even low‑level accounts) to run hidden commands that can read information from your database. This happens because the plugin does not properly check the data it receives. Update the plugin to a newer version or remove it until it is patched.

Original advisory text
WPML Multilingual CMS <= 4.9.5 - Incorrect Authorization to Authenticated (Subscriber+) SQL Injection via ‘elementIds’
The WPML Multilingual CMS plugin for WordPress is vulnerable to time-based SQL Injection via the ‘elementIds’ parameter in all versions up to, and including, 4.9.5 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. This vulnerability is exploitable due to an authorization bypass where the registered authorization callback fails to execute, allowing any authenticated user regardless of role to access administrative translation functionalities.
