CVE-2025-3914 is a vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) affecting the Aeropage Sync for Airtable plugin for WordPress. The flaw resides in the 'aeropage_media_downloader' function, which lacks proper validation of uploaded file types. This allows authenticated users with as low as Subscriber-level privileges to upload arbitrary files, including potentially malicious scripts, to the server hosting the WordPress site. Because the plugin does not restrict or sanitize the file types, attackers can upload executable files that may be used to execute remote code, leading to full server compromise. The vulnerability affects all versions up to and including 3.2.0. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and requiring only low privileges and no user interaction. While no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers seeking to gain persistent access or disrupt services on vulnerable WordPress sites. The lack of patch links suggests a fix may not yet be publicly available, increasing urgency for mitigation.

The impact of CVE-2025-3914 is significant for organizations running WordPress sites with the Aeropage Sync for Airtable plugin. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands, install backdoors, steal sensitive data, deface websites, or disrupt services. This compromises the confidentiality, integrity, and availability of the affected systems. Because the vulnerability requires only Subscriber-level access, it lowers the barrier for exploitation, potentially enabling attackers who have obtained low-privilege credentials or exploited other vulnerabilities to escalate their control. The widespread use of WordPress globally means many organizations, including e-commerce platforms, content publishers, and enterprises relying on Airtable integrations, could be affected. The absence of known exploits currently provides a window for proactive defense, but the high severity score indicates a critical need for remediation to prevent future attacks.

1. Immediately restrict or disable the Aeropage Sync for Airtable plugin until a patch is available. 2. Monitor and audit user accounts with Subscriber-level or higher privileges to detect suspicious activity or unauthorized file uploads. 3. Implement web application firewall (WAF) rules to detect and block suspicious file upload attempts targeting the 'aeropage_media_downloader' endpoint. 4. Enforce strict file type validation and sanitization at the server level for all uploads, including limiting allowed MIME types and scanning uploaded files for malicious content. 5. Harden server permissions to prevent execution of uploaded files in directories used for media storage. 6. Regularly update WordPress core, plugins, and themes to incorporate security patches as they become available. 7. Conduct penetration testing focused on file upload functionalities to identify similar vulnerabilities. 8. Educate site administrators and users about the risks of granting unnecessary privileges and encourage the principle of least privilege. 9. Maintain regular backups of website data and configurations to enable recovery in case of compromise.
