CVE-2025-50002 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in the Farost Energia WordPress theme, known as Energia. This issue affects versions from n/a through 1.1.2 and allows attackers to upload a web shell to the web server. Published on 2026-01-22, it carries a maximum CVSS v3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, and lack of prerequisites.

Remote, unauthenticated attackers can exploit this vulnerability over the network without user interaction. By uploading a dangerous file such as a web shell, they achieve high-impact compromise across confidentiality, integrity, availability, and scope change, potentially leading to full server control.

The Patchstack advisory documents this as an arbitrary file upload vulnerability in the WordPress Energia theme version 1.1.2.

Mitigating Controls (NIST 800-53 r5) AI

SI-3 Malicious Code Protection good match

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

CM-7 Least Functionality partial match

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.
