CVE-2023-48275Network attack vector

Authenticated arbitrary file upload via unchecked feature-request handler

Published Mar 26, 2024 · Updated Apr 28, 2026

Unrestricted file upload in Trustindex.io Widgets for Google Reviews 11.0.2 and earlier allows remote authenticated users to upload files. The feature-request handler in tabs/feature_request.php moves an uploaded file without validating its type, then attempts to unlink it. Editor-level access is required, and code execution depends on server load delaying unlink() after move_uploaded_file().
