What is CVE-2026-82187?

The Web to Print Online Designer WordPress plugin prior to version 2.15.0 lacks proper validation for the files being uploaded. This flaw allows unauthenticated attackers to upload any type of file, including malicious PHP scripts. Furthermore, the plugin inappropriately exposes access tokens to these uploads to any user, which can lead to unauthorized code execution on the server. Immediate action is required to secure installations running this plugin.

Affected Version(s)

Web to Print Online Designer 1.7.0 < 2.15.0
