What is CVE-2025-26936?

CVE-2025-26936 is a security vulnerability found in the Fresh Framework by NotFound, which is widely utilized for developing and managing web applications. This vulnerability involves improper control over code generation, known as code injection, which allows attackers to execute arbitrary code within the framework. Such a scenario could severely compromise an organization’s web applications, resulting in unauthorized access, data manipulation or even complete system takeover.

Technical Details

The vulnerability is categorized as a code injection issue and affects all versions of the Fresh Framework up to and including version 1.70.0. An attacker exploiting this flaw may potentially introduce malicious code into the application, leading to execution on the server side. The risk arises when user input is inadequately validated, allowing for unexpected commands to be executed within the application’s runtime context.

Potential Impact of CVE-2025-26936

1. Unauthorized Access: Attackers could gain control over the application, leading to unauthorized access to sensitive data and privileged functions within the organization’s systems.

2. Data Breaches: The ability to execute arbitrary code could result in data breaches, exposing confidential information stored in the affected applications, which can have legal and reputational consequences for organizations.

3. System Compromise: Successful exploitation can allow for the complete compromise of the application server, potentially enabling attackers to deploy malware, disrupt services, or pivot to other connected systems within the network infrastructure.
