{"id":"GHSA-w47m-j727-m843","summary":"Duplicate Advisory: Namespace value starting with / forms a protocol-relative URL when loadPath/addPath places {{ns}} right after a / (bypass of the // check added for GHSA-xvq9-wjp8-hwqf)","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-9jhj-wvmw-cfx5. This link is maintained to preserve external references.\n\n## Original Descriptioni18next-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injection and cross-site scripting.","modified":"2026-10-28T21:15:04.163851731Z","published":"2026-10-23T15:31:30Z","withdrawn":"2026-10-28T21:07:51Z","database_specific":{"github_reviewed_at":"2026-10-28T21:07:51Z","nvd_published_at":"2026-10-23T13:17:08Z","cwe_ids":["CWE-74"],"severity":"LOW","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/i18next/i18next-http-backend/security/advisories/GHSA-9jhj-wvmw-cfx5"},{"type":"WEB","url":"https://github.com/i18next/i18next-http-backend/security/advisories/GHSA-xvq9-wjp8-hwqf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115730"},{"type":"WEB","url":"https://github.com/i18next/i18next-http-backend/commit/042c3d4e4e9d73b2ae3aa76b22cb45d48f1e35b7"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/i18next-http-backend-4.0.2-protocol-relative-url-injection-via-namespace-in-interpolateurl"}],"affected":[{"package":{"name":"i18next-http-backend","ecosystem":"npm","purl":"pkg:npm/i18next-http-backend"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"4.0.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-w47m-j727-m843/GHSA-w47m-j727-m843.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/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"}]}
