## What is CVE-2025-12171?

CVE-2025-12171 is a high-severity vulnerability in anthonyeden RESTful Content Syndication, published on 1 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)
