The Velocity template engine, utilized by the affected product, accepts and processes template syntax without sufficient sanitization or validation of user-controlled input. This allows an authenticated administrator to inject arbitrary template syntax. Successful exploitation enables an attacker with administrative privileges to execute arbitrary template code on the server. This can lead to significant security consequences, including remote code execution, manipulation of data, and unauthorized access to sensitive information.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.4, indicating it requires adjacent network access with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from wso2 organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For wso2's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
