AI-suggested
Upgrade firebase-cli to version 13.6.0 or later, which contains the official fix for this vulnerability. Users running affected versions (>=3.6.1 <13.6.0) should update promptly to prevent potential data exfiltration via CSRF attacks. No other mitigations are specified or required.
Description
CVE-2024-4128 is a low-severity vulnerability in the Firebase CLI emulator suite that allows a potential Cross-Site Request Forgery (CSRF) attack. The issue arises from an export endpoint used to export data from running emulators. If a user runs the emulator and visits a malicious website on a browser that permits calls to localhost (notably Chrome versions before v94), the website could exfiltrate emulator data. This vulnerability affects firebase-cli versions from 3.6.1 up to but not including 13.6.0. The issue is fixed in version 13.6.0.
