What is CVE-2024-4128?

CVE-2024-4128 is a low-severity cross-site request forgery (CSRF) vulnerability in firebase-tools (npm), affecting versions < 13.6.0. It is fixed in 13.6.0. A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones.

How severe is CVE-2024-4128?

CVE-2024-4128 has a CVSS score of 2.6 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of firebase-tools are affected by CVE-2024-4128?

firebase-tools (npm) versions < 13.6.0 is affected.

Is there a fix for CVE-2024-4128?

Yes. CVE-2024-4128 is fixed in 13.6.0. Upgrade to this version or later.

Is CVE-2024-4128 exploitable, and should I be worried?

Whether CVE-2024-4128 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2024-4128 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

Firebase vulnerable to CRSF attack

This vulnerability was a potential CSRF attack. When running the Firebase emulator suite, there is an export endpoint that is used normally to export data from running emulators. If a user was running the emulator and navigated to a malicious website with the exploit on a browser that allowed calls to localhost (ie Chrome before v94), the website could exfiltrate emulator data. We recommend upgrading past version 13.6.0 or commit 068a2b08dc308c7ab4b569617f5fc8821237e3a0.

Impact

A victim's authenticated browser session is used to submit forged requests to an application that cannot distinguish them from legitimate ones. Typical impact: state-changing actions performed as the victim without their consent.

CVE-2024-4128 has a CVSS score of 2.6 (Low). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (13.6.0); upgrading removes the vulnerable code path.

Affected versions

firebase-tools (< 13.6.0)

Security releases

firebase-tools → 13.6.0 (npm)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
