CVE-2026-115730 · i18next-http-backend 4.0.2 Protocol-Relative URL Injection via Namespace in interpolateUrl

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
