If this cookie field is preset via an attacker by any other method, the attacker can manipulate the \"_authTokenSyncURL\" to point to their own server and it would allow an actor to capture user session data transmitted by the SDK. We recommend upgrading Firebase JS SDK at least to 10.9.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:A/VC:L/VI:L/VA:L/SC:H/SI:H/SA:H","score":5.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://firebase.google.com/support/release-notes/js#version_1090_-_march_14_2024","https://github.com/firebase/firebase-js-sdk/pull/8056"],"products":["google:firebase_javascript_sdk"],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-11023","score":0.00134,"percentile":0.02917,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3wf4-68gx-mph8","url":"https://osv.dev/vulnerability/GHSA-3wf4-68gx-mph8","summary":"Firebase JavaScript SDK allows attackers to manipulate the \"_authTokenSyncURL\" to point to their own server","modified":"2025-07-23T22:12:58Z","packages":[{"ecosystem":"npm","name":"firebase","purl":"pkg:npm/firebase","ranges":["<10.9.0"],"fixed":["10.9.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
