What is CVE-2025-2560?

The Ninja Forms WordPress plugin prior to version 3.10.1 is susceptible to a Stored Cross-Site Scripting (XSS) vulnerability. The plugin fails to properly sanitize and escape certain settings, allowing high privilege users, such as administrators, to execute malicious scripts. This risk persists even when the unfiltered_html capability is restricted, particularly in multisite configurations. If exploited, attackers can inject and store harmful scripts within the application, potentially compromising user data and security.

Affected Version(s)

Ninja Forms 0 < 3.10.1

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.
