Den mest alvorlige s\u00e5rbarhed (CVE-2025-32023) kan potentielt f\u00f8re til fjernudf\u00f8relse af kode p\u00e5 serveren ved at skrive data uden for det tildelte bufferomr\u00e5de. For at udnytte denne s\u00e5rbarhed skal en angriber have mulighed for at sende kommandoer til databasesystemet.         <\/p>\n<p>Problemet skyldes en fejl i implementeringen af kommandoer, der bruger HyperLogLog-algoritmen til at t\u00e6lle unikke elementer i et s\u00e6t. Ved at sende en specielt udformet streng kan en angriber initierer et buffer overflow. Problemet ber\u00f8rer alle versioner af Redis, der underst\u00f8tter HLL-kommandoer. Som en midlertidig beskyttelsesmetode kan adgangen til HLL-kommandoerne begr\u00e6nses gennem ACL.        <\/p>\n<p>Den anden s\u00e5rbarhed (CVE-2025-48367) kan udnyttes af en autentificeret bruger til at for\u00e5rsage serviceafbrydelser eller reducere databasesystemets ydeevne.
