워드프레스 결제 심플페이 <= 5.2.0 - Authenticated (Contributor+) Local File Inclusion

The 워드프레스 결제 심플페이 plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 5.2.0. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: 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: 워드프레스 결제 심플페이 5.2.2 closes this, and updating the plugin is the step that ends it.
