{"id":"CVE-2025-68157","aliases":["GHSA-38r7-794h-5758"],"url":"https://o3.security/vulnerability/CVE-2025-68157","summary":"webpack buildHttp HttpUriPlugin allowedUris bypass via HTTP redirects","details":"Webpack is a module bundler. From version 5.49.0 to before 5.104.0, when experiments.buildHttp is enabled, webpack’s HTTP(S) resolver (HttpUriPlugin) enforces allowedUris only for the initial URL, but does not re-validate allowedUris after following HTTP 30x redirects. As a result, an import that appears restricted to a trusted allow-list can be redirected to HTTP(S) URLs outside the allow-list. This is a policy/allow-list bypass that enables build-time SSRF behavior (requests from the build machine to internal-only endpoints, depending on network access) and untrusted content inclusion in build outputs (redirected content is treated as module source and bundled). This issue has been patched in version 5.104.0.","published":"2026-02-05T23:08:13.214Z","modified":"2026-07-15T01:49:18.632216382Z","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"webpack","fixedVersion":"5.104.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68157.json"},{"type":"ADVISORY","url":"https://github.com/webpack/webpack/security/advisories/GHSA-38r7-794h-5758"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68157"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:18.632216382Z"}}
