CVE-2026-97871 Zhonglun CVE debrief

Who should care

Defenders of systems using CloudPos, specifically those with remote access to JSBridge functionality, should assess exposure and prioritize verification of affected systems, considering potential impacts on system compromise and necessary compensating controls. They must also review compensating controls for exposed systems while remediation is scheduled and verified.

Why it matters

CVE-2026-97871 is a remote code injection vulnerability in CloudPos's JSBridge. Defenders of systems using CloudPos should assess exposure, prioritize verification of affected systems, and implement compensating controls. Evidence is limited, and vendor remediation details are unknown.

• Remote code injection may lead to system compromise
• Defenders must verify if systems are using affected versions up to 3.0.1.76
• Implementing compensating controls to restrict access to JSBridge functionality is crucial

Technical summary

The OpenLocalBrowser function in JSBridge of Zhonglun CloudPos up to 3.0.1.76 is vulnerable to code injection. The attack can be executed remotely by manipulating the url argument. This vulnerability may lead to system compromise. Defenders must verify if systems are using affected versions up to 3.0.1.76 and implement compensating controls to restrict access to JSBridge functionality.
