Prior to 9.7.0, the HTTP redirect handler (HttpExecutor.prepareRedirectUrlOptions) only stripped a credential header whose key string matched exactly lowercase \"authorization\", exposing credentials. Other credential-bearing headers — most notably PRIVATE-TOKEN (used by GitLab's personal access token flow) and mixed-case Authorization (used by GitLab's Bearer/OAuth flow) — were not stripped and could be forwarded to an attacker-controlled cross-origin redirect destination. This issue has been fixed in version 9.7.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","score":8.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/electron-userland/electron-builder/commit/22a7532bd01b9fb42cff7c58d599c7ad683569fe","https://github.com/electron-userland/electron-builder/security/advisories/GHSA-p2f4-r6v6-j797","https://github.com/electron-userland/electron-builder/security/advisories/GHSA-p2f4-r6v6-j797"],"products":["electron:builder-util-runtime","electron:electron-builder"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-54673","score":0.00407,"percentile":0.35028,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p2f4-r6v6-j797","url":"https://osv.dev/vulnerability/GHSA-p2f4-r6v6-j797","summary":"electron-updater: Cross-origin redirect leaks `PRIVATE-TOKEN` and mixed-case `Authorization` credentials in `builder-util-runtime`","modified":"2026-07-24T14:16:01.807017022Z","packages":[{"ecosystem":"npm","name":"builder-util-runtime","purl":"pkg:npm/builder-util-runtime","ranges":["<9.7.0"],"fixed":["9.7.0"]}]}],"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).
