# CVE-2025-12171: RESTful Content Syndication 1.1.0 - 1.5.0 - Authenticated (Contributor+) Arbitrary File Upload

- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no

## Affected

- anthonyeden RESTful Content Syndication: from 1.1.0, through 1.5.0

## 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.
