Vulnerability Overview

The sina-extension-for-elementor plugin before 2.2.1 for WordPress has local file inclusion.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

Reaching this weakness in Sina Extension for Elementor < 2.2.1 takes a caller who can reach the endpoint. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.

Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For Sina Extension for Elementor the fix is 2.2.1: builds < 2.2.1 are affected, anything from 2.2.1 onward is not.

Remediation

Update to version 2.2.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Sina Extension for Elementor: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Sina Extension for Elementor 2.2.1 closes this, and updating the plugin is the step that ends it.
