CVE-2026-115730
Description
A flaw was found in i18next-http-backend. A remote attacker who can control namespace values can supply input starting with a slash to construct protocol-relative URLs in path templates. This flaw allows translation requests to be redirected to an attacker-controlled server, leading to cross-site scripting (XSS) and unauthorized user interface content injection.
Statement
This vulnerability is rated as having Low severity for Red Hat products because successful exploitation requires highly specific conditions that are not present in standard deployments. In Red Hat web consoles and management interfaces, translation namespaces and path configurations are hardcoded internally rather than populated from untrusted external user input. Furthermore, default path templates prefix namespaces with fixed directory paths rather than placing them directly after a root slash, preventing the formation of protocol-relative redirect URLs.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
