What is CVE-2026-16567?

The Document Embedder plugin for WordPress prior to version 2.3.1 has a significant security flaw that allows unauthenticated users to exploit the file download feature. This vulnerability arises because the plugin fails to validate the status of documents before generating a download token. As a result, attackers can potentially access and download confidential documents, including those that are private or still in draft mode, simply by iterating through document IDs. It's crucial for users to update their plugin to the latest version to mitigate this risk.

Affected Version(s)

Document Embedder 0 < 2.3.1

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.
