Template Injection Vulnerability in Kong Insomnia Desktop Application

CVE-2025-1087

What is CVE-2025-1087?

CVE-2025-1087 is a significant vulnerability affecting the Kong Insomnia Desktop Application prior to version 11.0.2. This desktop application serves as a powerful tool for API development, allowing users to design, debug, and test APIs easily. The vulnerability exists due to insufficient validation of user input when processing template strings, which could allow attackers to execute arbitrary JavaScript code within the context of the application. Such an exploit could lead to severe security breaches, as it would enable unauthorized actions to be performed within the application, potentially compromising sensitive data and functionality critical to software development activities.

Potential impact of CVE-2025-1087

1. Arbitrary Code Execution: The main impact of this vulnerability is the potential for attackers to execute arbitrary code. This could allow them to manipulate the application’s environment, leading to unauthorized access and control over systems integrated with Kong Insomnia.

2. Data Breaches: The ability to execute arbitrary code could lead to exposure of sensitive information stored within the application or related infrastructure, resulting in data breaches and loss of confidentiality.

3. Compromise of Development Environment: As Kong Insomnia is primarily used in API development, an exploitation of this vulnerability could jeopardize the integrity of the development environment, allowing malicious actors to inject vulnerabilities into APIs and applications that rely on them, further escalating the risk to organizations utilizing these tools.
