{"id":"UBUNTU-CVE-2026-115730","details":"i18next-http-backend 4.0.2 contains an incomplete fix in interpolateUrl() that allows attackers to redirect translation requests by supplying an ns value starting with a slash. Attackers controlling the namespace value can form a protocol-relative URL in loadPath or addPath templates to load attacker-hosted translations, enabling UI content injection and cross-site scripting.","modified":"2026-10-27T04:17:48.076798939Z","published":"2026-10-26T00:00:00Z","upstream":["CVE-2026-115730"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-115730"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-115730"},{"type":"REPORT","url":"https://github.com/i18next/i18next-http-backend/commit/042c3d4e4e9d73b2ae3aa76b22cb45d48f1e35b7"},{"type":"REPORT","url":"https://github.com/i18next/i18next-http-backend/security/advisories/GHSA-9jhj-wvmw-cfx5"},{"type":"REPORT","url":"https://github.com/i18next/i18next-http-backend/security/advisories/GHSA-xvq9-wjp8-hwqf"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/i18next-http-backend-4.0.2-protocol-relative-url-injection-via-namespace-in-interpolateurl"}],"affected":[{"package":{"name":"node-i18next-http-backend","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-i18next-http-backend?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.21+dfsg-1","1.3.1+dfsg-2","1.3.1+dfsg-3","1.3.1+dfsg-4","1.3.2+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.3.2+dfsg-1","binary_name":"libjs-i18next-http-backend"},{"binary_version":"1.3.2+dfsg-1","binary_name":"node-i18next-http-backend"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115730.json"}},{"package":{"name":"node-i18next-http-backend","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-i18next-http-backend?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.1-1","2.4.1+ds-2","2.4.1+ds-2build2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.1+ds-2build2","binary_name":"libjs-i18next-http-backend"},{"binary_version":"2.4.1+ds-2build2","binary_name":"node-i18next-http-backend"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115730.json"}},{"package":{"name":"node-i18next-http-backend","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/node-i18next-http-backend?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1+ds-2build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-i18next-http-backend","binary_version":"2.4.1+ds-2build2"},{"binary_name":"node-i18next-http-backend","binary_version":"2.4.1+ds-2build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115730.json"}},{"package":{"name":"node-i18next-http-backend","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-i18next-http-backend?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1+ds-2build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libjs-i18next-http-backend","binary_version":"2.4.1+ds-2build2"},{"binary_version":"2.4.1+ds-2build2","binary_name":"node-i18next-http-backend"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-115730.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
