RESTful Content Syndication 1.1.0 - 1.5.0 - Authenticated (Contributor+) Arbitrary File Upload

Unrestricted Upload of File with Dangerous Type
CVE CVE-2025-12171
CVSS High (8.8)
Publicly Published October 31, 2025

Description

The RESTful Content Syndication plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ingest_image() function in versions 1.1.0 to 1.5.0. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This requires the attacker have access to a defined third-party server as specified in the settings, so it is unlikely that this will be exploitable by contributor-level users, and more likely to be exploited by administrators who also have access to the plugin's settings.
