CVE-2017-7653 describes a denial-of-service vulnerability in Eclipse Mosquitto broker versions up to 1.4.15, where the broker fails to reject non-UTF-8 topic strings. A low-privileged attacker can exploit this by sending a malformed topic string, causing other clients that enforce UTF-8 validation to disconnect from the broker. This medium-severity vulnerability (CVSS 5.3) has a high attack complexity and impacts availability, but there is no evidence of active exploitation, public exploit code, or significant community discussion.
