CVE-2026-82973

Estado: Pendiente de análisisCrítica (9.4)—

Improper neutralization of CRLF sequences in IMAP command construction in psyb0t/docker-mailbox before 0.4.13 allows a remote unauthenticated attacker, when bearer-token authentication is not configured, to inject additional IMAP commands into an authenticated upstream mailbox connection via crafted folder, UID, or search values.

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.

Aplicación expuesta remotamente sin autenticación (AV:N, PR:N, UI:N). Inyección CRLF en comandos IMAP permite ejecución de comandos arbitrarios en conexión autenticada aguas arriba, con impacto en integridad y disponibilidad.

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.
