Overview
In the world of cybersecurity, few things are as damaging as vulnerabilities within widely-used platforms such as WordPress. Among the most recent security issues is the CVE-2025-2932 vulnerability found in the JKDEVKIT plugin for WordPress. This plugin, popular for various website development tasks, has been found to have a serious flaw that could potentially lead to system compromise or data leakage.
The vulnerability affects all versions of the JKDEVKIT plugin up to, and including, 1.9.4 and is dangerous due to its potential for arbitrary file deletion. This blog post seeks to provide a detailed technical overview of this vulnerability, including how it works, who it affects, and how to mitigate its risks.

How the Exploit Works
This vulnerability stems from insufficient file path validation in the ‘font_upload_handler’ function within the JKDEVKIT plugin for WordPress. As a result, an authenticated attacker with subscriber-level access and above can delete arbitrary files on the server. When the right file, such as wp-config.php, is deleted, it can pave the way for remote code execution, potentially leading to system takeover.
If WooCommerce is enabled, attackers will need a higher privilege level – contributor-level access and above. This makes the vulnerability less likely to be exploited in this scenario, but the potential impact remains high.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited:
POST /wp-content/plugins/jkdevkit/font_upload_handler.php HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "file_path": "/absolute/path/to/wp-config.php" }The above HTTP request attempts to delete the “wp-config.php” file, which can potentially lead to remote code execution.
Mitigation Guidance
The most effective way to mitigate this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Additionally, restricting user privileges and closely monitoring server logs for suspicious activity can help prevent exploitation of this vulnerability.
