    CVE-2026-85058 (GCVE-0-2026-85058)

    Vulnerability from nvd – Published: 2026-09-18 17:40 – Updated: 2026-09-18 17:40

    Title
    Moquette: Missing Authorization in io.moquette:moquette-broker
    Summary
    Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, PostOffice.publishWill publishes a client-controlled Last Will message through publish2Subscribers without invoking the authorizator.canWrite check used by normal PUBLISH paths. When anonymous access is enabled and topic ACLs restrict writes, a remote client can set an ACL-protected topic as the Last Will Topic during CONNECT and perform an abnormal client disconnect, causing the broker to inject attacker-controlled messages into a topic for which the client lacks write permission. This issue is fixed in version 0.18.1.
