What is CVE-2025-34083?

The AIT CSV Import/Export plugin for WordPress versions up to 3.0.3 contains an unrestricted file upload vulnerability that allows attackers to upload arbitrary files through the upload-handler.php endpoint. This endpoint lacks proper authentication and content-type validation, enabling malicious PHP files to be uploaded directly to the server. Despite the potential for upload errors related to CSV files, these malicious files are stored in the wp-content/uploads/ directory and remain executable. Notably, this vulnerability can be exploited even if the plugin is inactive, raising significant security concerns for WordPress sites utilizing this plugin.

Affected Version(s)

AIT CSV Import/Export WordPress Plugin * <= 3.0.3
