CVE-2025-12171Network attack vector

Authenticated arbitrary file upload via unvalidated image ingestion

Published Nov 1, 2025 · Updated Nov 1, 2025

Arbitrary file upload in RESTful Content Syndication 1.1.0 through 1.5.0 allows remote authenticated users to place files on the server. The ingest_image() function downloads content presented as an image from the configured master WordPress site and stores it locally without validating that the response is an image. Author-level access and control of the configured master site are required; executing a server-interpreted upload grants remote code execution.
