Frappe Framework before 15.111.0 and 16.x before 16.21.0 Server-Side Template Injection via Message Fields

Summary

Frappe Framework before 15.111.0 and 16.x before 16.21.0 contains a server-side template injection vulnerability because user-controlled message fields are rendered as templates without neutralization. An authenticated attacker holding a common operational role can inject template expressions that the server evaluates in an unrestricted context.

Remediation

1. Inventory every frappe frappe deployment, including staging.
2. Upgrade frappe frappe to the fixed version for your release line, listed under Affected versions.
3. Confirm the running version after the upgrade.
