CVE-2026-107700 ntharim CVE debrief

Who should care

Node.js developers and administrators using dot-access versions 0.0.3 through 1.0.0 should assess exposure and take mitigation steps. This includes verifying the version of dot-access in use, restricting input to the get() function, and monitoring the Node.js process for suspicious activity. Security teams and vulnerability management teams should also review the vulnerability and implement necessary mitigations.

Why it matters

CVE-2026-107700 is a critical vulnerability in dot-access that allows remote code injection. Node.js deployments using affected versions should verify exposure and apply patches or mitigations.

• Potential for arbitrary code execution
• Elevation of privileges in Node.js process
• Possible data breaches or system compromise

Technical summary

The dot-access package is vulnerable to code injection via the get() path argument. An attacker can supply a crafted path to execute JavaScript, potentially leading to arbitrary code execution. This vulnerability allows remote attackers to execute JavaScript by supplying crafted paths to the get() function. The path is concatenated into a new Function body in index.js, enabling attackers to access constructor.constructor and load child_process to run operating system commands in the Node.js process. Affected Node.js deployments should assess exposure and take mitigation steps.

Defensive priority

High priority for Node.js deployments using dot-access versions 0.0.3 through 1.0.0; verify exposure and apply patches or mitigations.

Recommended defensive actions

• Verify dot-access version and upgrade to a patched version if possible
• Review and restrict input to the get() function to prevent crafted paths
• Monitor Node.js process for suspicious activity
• Perform a thorough review of the system's exposure to the vulnerability
• Implement compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions and retest remediated assets
• Review relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and source item provide details on the vulnerability, affected versions, and references to additional information. The vulnerability exists in dot-access versions 0.0.3 through 1.0.0.
