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.
