From version 5.49.0 to before 5.104.1, when experiments.buildHttp is enabled, webpack’s HTTP(S) resolver (HttpUriPlugin) can be bypassed to fetch resources from hosts outside allowedUris by using crafted URLs that include userinfo (username:password@host). If allowedUris enforcement relies on a raw string prefix check (e.g., uri.startsWith(allowed)), a URL that looks allow-listed can pass validation while the actual network request is sent to a different authority/host after URL parsing. This is a policy/allow-list bypass that enables build-time SSRF behavior (outbound requests from the build machine to internal-only endpoints, depending on network access) and untrusted content inclusion (the fetched response is treated as module source and bundled). This issue has been patched in version 5.104.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N","score":3.7},"cwes":["CWE-918"],"references":["https://github.com/webpack/webpack/security/advisories/GHSA-8fgc-7cc6-rx7x"],"products":["webpack.js:webpack"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2025-68458","score":0.0023,"percentile":0.13824,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-8fgc-7cc6-rx7x","url":"https://osv.dev/vulnerability/GHSA-8fgc-7cc6-rx7x","summary":"webpack buildHttp: allowedUris allow-list bypass via URL userinfo (@) leading to build-time SSRF behavior","modified":"2026-09-10T03:50:34.472343977Z","packages":[{"ecosystem":"npm","name":"webpack","purl":"pkg:npm/webpack","ranges":[">=5.49.0 <5.104.1"],"fixed":["5.104.1"]}]}],"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).
