Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the interpolateUrl function in lib/utils.js, where a namespace value containing a leading / (permitted for nested namespaces) can combine with the template's own leading / to produce a protocol-relative URL of the form //evil.example/en.json. Browsers treat such URLs as cross-origin requests, allowing an attacker who controls the namespace parameter to redirect translation resource fetches to an arbitrary host and potentially influence application content.
