Deeper analysis
CVE-2025-11170 is an arbitrary file upload vulnerability in the WP移行専用プラグイン for CPI plugin for WordPress, affecting all versions up to and including 1.0.2. The flaw arises from missing file type validation in the Cpiwm_Import_Controller::import function, allowing attackers to upload arbitrary files to the affected site's server. It is rated critical with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-434 (Unrestricted Upload of File with Dangerous Type). The vulnerability was published on 2025-11-11.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction or privileges required. By leveraging the import function, they can upload malicious files, which may lead to remote code execution on the server depending on the file type and server configuration.
