What is CVE-2026-12514?

The Shared Files and shared-files-pro plugins for WordPress are susceptible to a file upload vulnerability due to the lack of proper capability checks in their file-upload handler. This handler is accessible to unauthenticated users and relies solely on a nonce shown on public pages for protection. This oversight allows unauthenticated visitors to upload files to a publicly accessible directory, potentially exposing sensitive server information through the response. While uploads are restricted to permissible MIME types, this still presents significant security risks that need to be mitigated to ensure the safety of WordPress sites.

Affected Version(s)

Shared Files 0 < 1.7.67

shared-files-pro 0 < 1.7.70

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
