CVE-2026-9100

The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an out-of-bounds read).

Summary		(es) El API GridFS heredada del controlador C de MongoDB acepta metadatos de archivo malformados de la base de datos sin validación adecuada. Documentos manipulados en una colección GridFS pueden causar que cualquier aplicación que lea esos archivos a través de la API heredada se bloquee (a través de una división por cero) o filtre silenciosamente el contenido de la memoria del proceso (a través de una lectura fuera de límites).
