Prototype Pollution

Overview i18next-fs-backend is an i18next-fs-backend is a backend layer for i18next using in Node.js and for Deno to load translations from the filesystem. Affected versions of this package are vulnerable to Prototype Pollution via the getLastOfPath method. An attacker can modify global object...

CVE-2026-48714

i18next-http-middleware is a middleware to be used with Node.js web frameworks like express or Fastify and also for Deno. In versions prior to 3.9.7, the missingKeyHandler blocked the literal request-body keys proto, constructor, and prototype added in 3.9.3, see GHSA-5fgg-jcpf-8jjw, but did not...

CVE-2026-48713

Versions prior to 2.6.6 are vulnerable to prototype pollution via crafted missing-key strings when used to persist missing translation keys e.g. via i18next-http-middleware's missingKeyHandler exposed to untrusted input. Backend.writeFile splits each queued missing-key string on the configured...
