CVE-2023-37979Public exploitNetwork attack vector

Reflected script execution via unrestricted method override

Published Jul 27, 2023 · Updated Apr 28, 2026

Reflected XSS in Saturday Drive Ninja Forms 3.6.25 and earlier allows remote attackers to execute scripts via a crafted POST request. The nf_batch_process route accepts an attacker-controlled method_override that invokes _respond, which emits the unsanitized data parameter in a text/html response. Exploitation requires a user to submit attacker-controlled content; script execution occurs in that user's WordPress origin.
