CVE-2021-22911

Estado: ModificadaCrítica (9.8)—💥 Exploit

A improper input sanitization vulnerability exists in Rocket.Chat server 3.11, 3.12 & 3.13 that could lead to unauthenticated NoSQL injection, resulting potentially in RCE.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
