CVE-2026-109652 PUBLISHED

Frappe ERPNext before 15.119.1 Server-Side Template Injection via Message Fields

Assigner: VulnCheck
Reserved: 12.10.2026 Published: 12.10.2026 Updated: 12.10.2026

Frappe ERPNext before 15.119.1 and 16.x before 16.32.0 contains a server-side template injection vulnerability because user-controlled message fields are not validated before template rendering, allowing expressions to run in an unrestricted context. Authenticated attackers holding a common operational role can inject template expressions to read and write arbitrary database data, delete documents, send outbound requests from the server, and send mail from the site.
