CVE-2026-80440: Unknown Hustle

Medium severity, CVSS 4.8. EPSS: 0.2% chance of exploitation in the next 30 days.

The Hustle WordPress plugin before 7.8.14.2 does not prevent shortcodes in submitted form values from being executed when it substitutes those values into the message it returns after submission, because the guard it applies can be defeated by nesting, allowing unauthenticated users to run any shortcode registered on the site.

Affected products

• Unknown Hustle: from 7.0.0.1, before 7.8.14.2 (fixed in 7.8.14.2)
