CVE-2026-74761

Estado: AnalizadaAlta (7.5)—

Improper input validation in TopicRegion in Apache ActiveMQ, Apache ActiveMQ Broker, and Apache ActiveMQ All on all platforms.

An authenticated client can spoof clientId when removing a durable topic subscription.

This issue affects Apache ActiveMQ Broker: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ All: before 5.19.11, from 6.0.0 before 6.3.2; Apache ActiveMQ: before 5.19.11, from 6.0.0 before 6.3.2.

Users are recommended to upgrade to version 6.3.2 or 5.19.11 which fixes the issue.

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.

Validación impropia permite a cliente autenticado falsificar clientId en suscripción durable (AV:N/AC:L/PR:N): manipulación de datos. Afecta integridad sin requerir privilegios previos (I:H).

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.
