CVE-2024-4128: Google Firebase Command Line Interface

Medium severity, CVSS 4.3. EPSS: 0.1% chance of exploitation in the next 30 days.

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 https://github.com/firebase/firebase-tools/commit/068a2b08dc308c7ab4b569617f5fc8821237e3a0

Affected products

• Google Firebase Command Line Interface: before 13.6.0 (fixed in 13.6.0)
