CVE-2023-6316
CWE-434Published: January 11, 2024· Updated: Jun 17, 2026
Official Description
The MW WP Form plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the '_single_file_upload' function in versions up to, and including, 5.0.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
Risk Analysis
The MW WP Form plugin for WordPress contains a flaw that allows unauthenticated users to upload arbitrary files to the server. This vulnerability is rated as critical due to the potential for remote code execution, which could lead to a full system compromise.
There is no known public exploit for this vulnerability, and it is not listed in CISA's KEV catalog. However, it is remotely exploitable with low attack complexity.
Users should ensure they are running a version of the MW WP Form plugin beyond 5.0.1. Administrators should also restrict file upload permissions and implement strict file type validation.
Technical Analysis
CVE-2023-6316 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
