CVE-2025-71395

SurrealDB versions before 2.2.2 contain a memory exhaustion vulnerability in the string::replace function that fails to restrict resulting string length when using regex patterns. An authenticated attacker can craft a malicious query to exhaust server memory through unbounded string allocations, causing denial of service.

Summary		(es) Las versiones de SurrealDB anteriores a la 2.2.2 contienen una vulnerabilidad de agotamiento de memoria en la función string::replace que no restringe la longitud de la cadena resultante al usar patrones de expresiones regulares. Un atacante autenticado puede crear una consulta maliciosa para agotar la memoria del servidor a través de asignaciones de cadenas ilimitadas, causando denegación de servicio.
