{"id":"GHSA-3wf4-68gx-mph8","summary":"Firebase JavaScript SDK allows attackers to manipulate the \"_authTokenSyncURL\" to point to their own server","details":"Firebase JavaScript SDK utilizes a \"FIREBASE_DEFAULTS\" cookie to store configuration data, including an \"_authTokenSyncURL\" field used for session synchronization.  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 am actor to capture user session data transmitted by the SDK. We recommend upgrading Firebase JS SDK at least to 10.9.0.","aliases":["CVE-2024-11023"],"modified":"2025-07-23T22:12:58Z","published":"2024-11-18T12:30:42Z","database_specific":{"github_reviewed_at":"2024-11-18T20:04:30Z","nvd_published_at":"2024-11-18T11:15:05Z","cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-11023"},{"type":"WEB","url":"https://github.com/firebase/firebase-js-sdk/pull/8056"},{"type":"WEB","url":"https://github.com/firebase/firebase-js-sdk/commit/245dd26e19b6c16aca7e1b7e597ed5784c2984ba"},{"type":"WEB","url":"https://firebase.google.com/support/release-notes/js#version_1090_-_march_14_2024"},{"type":"PACKAGE","url":"https://github.com/firebase/firebase-js-sdk"}],"affected":[{"package":{"name":"firebase","ecosystem":"npm","purl":"pkg:npm/firebase"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"10.9.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/11/GHSA-3wf4-68gx-mph8/GHSA-3wf4-68gx-mph8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
