CVE-2026-21448Public exploitNetwork attack vector

Authenticated code execution via checkout address templates

Published Jan 2, 2026 · Updated Jan 2, 2026

Server-side template injection in Webkul Bagisto before 2.3.10 allows remote authenticated users to execute code through checkout addresses. Checkout address fields store template expressions without neutralizing their syntax, and the admin order view evaluates the stored values. A customer account and an order or saved address are sufficient; successful payloads execute in the application server's context.
