Last updated on: 2026-03-06

Assigner: WSO2 LLC

Description
Due to the use of a vulnerable third-party Velocity template engine, a malicious actor with admin privilege may inject and execute arbitrary template syntax within server-side templates. Successful exploitation of this vulnerability could allow a malicious actor with admin privilege to inject and execute arbitrary template code on the server, potentially leading to remote code execution, data manipulation, or unauthorized access to sensitive information.

Executive Summary

This vulnerability arises from the use of a vulnerable third-party Velocity template engine. It allows a malicious actor who already has admin privileges to inject and execute arbitrary template syntax within server-side templates.

By exploiting this flaw, the attacker can run arbitrary template code on the server, which can lead to serious security issues such as remote code execution, data manipulation, or unauthorized access to sensitive information.

Impact Analysis

The impact of this vulnerability can be severe. An attacker with admin privileges could execute arbitrary code on the server remotely, manipulate data, or gain unauthorized access to sensitive information.

  • Remote code execution on the server
  • Data manipulation
  • Unauthorized access to sensitive information
