CVE-2025-71391

Estado: AnalizadaAlta (7.1)—

SurrealDB versions before 2.2.2 contain an uncaught exception vulnerability in the net module that allows authenticated users to crash the database. Attackers can send crafted HTTP queries containing null bytes to the /sql endpoint, causing an unhandled exception that crashes the SurrealDB instance and any dependent applications.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Inferido por reglas deterministas a partir del vector CVSS y la CWE. Solo orientativo.
