CVE-2026-71498
Full vulnerability record from the local CVENow database.
Description
node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated (incomplete) multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final, incomplete code point. This could result in an out-of-bounds read and potential disclosure of adjacent memory contents. This issue is fixed in version 1.26.1.

Antes de la versión 1.26.1, pasar un Buffer cuyos bytes finales formaran una secuencia UTF-8 multibyte truncada (incompleta) podría causar que el enlace nativo leyera más allá del final del buffer asignado mientras intentaba decodificar el punto de código final e incompleto. Esto podría resultar en una lectura fuera de límites y una posible divulgación del contenido de memoria adyacente. Este problema está solucionado en la versión 1.26.1."
