CVE-2026-34156 Scanner

NocoBase is a powerful framework for building database management systems, often utilized by developers and IT teams in various enterprises. It is widely used to streamline application development and workflow automation. Companies often leverage NocoBase for its flexibility and integration capabilities, enhancing operational efficiency. The software allows for seamless collaboration and data management across multiple platforms. As an open-source framework, it receives contributions and enhancements from a vast community. Its capacity for customization makes it a preferred choice for many global enterprises needing tailored data solutions.

The Remote Code Execution (RCE) vulnerability in NocoBase poses a significant threat, allowing authenticated users to execute arbitrary code with root privileges. This occurs due to improper sandboxing of user-supplied JavaScript code in the Node.js environment. Attackers can exploit the vulnerability by accessing WritableWorkerStdio stream objects to escape the sandbox. The vulnerability spans various versions that precede the patched version, making it essential for users to update to protect against potential exploitation. As RCE vulnerabilities provide a powerful vector for unauthorized access, they are often prioritized for immediate remediation to prevent data breaches.

Technical analysis reveals that the RCE vulnerability in NocoBase allows attackers to utilize the console object to access the underlying operating system. By manipulating the prototype chain, malicious code can bypass restrictions in place, executing commands at the same privilege level as the application. The affected API endpoint is /api/flow_nodes:test, which processes and executes the script node. The vulnerability exploits specific JavaScript constructors, bridging the gap from the sandboxed environment to the host system's command execution. To achieve this, attackers require authentication but, once within the system, they can escalate their privileges, significantly impacting system security.

Exploiting the RCE vulnerability in NocoBase could lead to severe consequences, including unauthorized access to sensitive information, data loss, or system manipulation by attackers. It might allow threat actors to deploy malware, extract confidential data, or disrupt services. System administrators should prioritize mitigating these risks by updating to secure versions and reviewing audit logs. Unchecked, such vulnerabilities can compromise the integrity, confidentiality, and availability of the system, undermining user trust and potentially resulting in financial or reputational damage.
