Vulnerability from github – Published: 2026-10-23 15:31 – Updated: 2026-10-23 15:31

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.

Severity

3.1 (Low)
