CVE-2025-12138Network attack vector

Authenticated arbitrary file upload via trusted Content-Type

Published Nov 21, 2025 · Updated Nov 21, 2025

Arbitrary file upload in Infinite Uploads URL Image Importer 1.0 through 1.0.6 allows remote authenticated users to upload PHP files via image URLs. The uimptr_import_image_from_url() function trusts the remote server's Content-Type header and writes the response to the uploads directory before validating its actual type. Author-level access and control of a remote response are required; a stored PHP file permits code execution when the server executes files from that directory.
