CVE-2026-93737
Azkaban through 4.0.0 omits project permission checks in the ScheduleServlet fetchSchedule action, allowing authenticated users to read any project's schedule configuration. Attackers can supply arbitrary project and flow identifiers to retrieve sensitive schedule details including execution times, cron expressions, flow parameters, and notification email lists without proper authorization.
CVSS

- Puntuación base: 7.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.54%
- Percentil entre todas las CVEs puntuadas: 44
- Fecha de la puntuación: 5/10/2026
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.
- Explotación
T1210Exploitation of Remote Serviceslateral movement75 % - Impacto principal
T1005Data from Local Systemcollection85 % - Impacto secundario
T1552.007Container APIcredential access70 %
Azkaban requiere autenticación (PR:L) y acceso remoto (AV:N) a un servicio para explotar falta de validación de permisos. El impacto es lectura no autorizada de configuraciones sensibles (horarios, parámetros, emails) sin verificación de acceso al proyecto.
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.
