CVE-2026-90944

Estado: AplazadaAlta (8.8)—

Krayin CRM through 2.2.6 exposes the POST /admin/mail/inbound-parse endpoint without authentication, allowing unauthenticated attackers to inject arbitrary emails into the CRM inbox. Attackers can supply crafted RFC 2822 messages with forged sender information and headers to insert emails with any subject and body, including replies to existing conversation threads.

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.

Endpoint POST sin autenticación (AV:N, PR:N, UI:N) permite inyección de emails. Impacta autenticación (suplantación de identidad vía headers falsificados) y manipulación de datos (inyección de contenido en bandeja de entrada).

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.
