CVE-2026-56747

Estado: AnalizadaAlta (8.7)—

Improper control of generation of code in the JSON Pointer-to-accessor compiler in Cribl Stream before 4.18.2 allows a remote authenticated attacker with edit privileges to execute arbitrary JavaScript on the server via a crafted database connection identifier or pack configuration value.

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.

Acceso de red (AV:N) con autenticación (PR:L) sin interacción del usuario permite explotar CWE-94 (code generation injection) en el compilador JSON Pointer para ejecutar JavaScript arbitrario en el servidor Cribl Stream.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
