What is CVE-2026-16573?

The Bit Form WordPress plugin prior to version 3.2.0 allows unauthenticated users to upload malicious SVG files that contain JavaScript code. When these files are viewed, the embedded code can execute within the context of the user’s browser session, potentially leading to unauthorized actions and data exposure. This vulnerability highlights the importance of file sanitization to prevent harmful scripts from being executed on your website.

Affected Version(s)

Bit Form 0 < 3.2.0

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.
