WordPress vulnerability analysis and mitigation

The RESTful Content Syndication plugin for WordPress (versions 1.1.0 to 1.5.0) contains a vulnerability (CVE-2025-12171) that allows arbitrary file uploads due to missing file type validation in the ingest_image() function. This vulnerability was discovered on October 31, 2025, and was reported by security researcher kr0d (Wordfence).

The vulnerability stems from insufficient file type validation in the ingest_image() function. The issue has been assigned a CVSS v3.1 score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The vulnerability is classified as CWE-434 (Unrestricted Upload of File with Dangerous Type) (NVD).

When exploited, this vulnerability allows authenticated attackers with Author-level access and above to upload arbitrary files to the affected site's server, potentially enabling remote code execution. The impact is heightened for administrators who have access to the plugin's settings and a defined third-party server (NVD).

The vulnerability has been patched in version 1.6.0 of the plugin, which implements proper file type validation checks. Users are advised to update to this version immediately (WordPress Plugin).
