What it is

The WP Import Export Lite WordPress plugin before 3.9.33 does not properly validate URLs before requesting them during the import process, allowing users with the import capability, which administrators hold by default, to make the site issue requests to internal hosts and services and read their responses. This is an incomplete fix for CVE-2026-11397.
