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.\n\n## Affected packages\n\n- `i18next-http-backend <= 4.0.2`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":17,"depthScoreParts":{"impact":17.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
