What is CVE-2026-80440?

The Hustle plugin for WordPress prior to version 7.8.14.2 contains a security flaw that permits unauthenticated users to execute shortcodes through form submissions. The plugin fails to sufficiently sanitize shortcodes in user-provided input, allowing potential attackers to exploit this weakness by nesting shortcodes. This can lead to unauthorized access and control over the content rendered on the website, posing significant security risks.

Affected Version(s)

Hustle 7.0.0.1 < 7.8.14.2

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.
