CVE-2026-21888 HIGH This Week

NanoMQ MQTT Broker versions 0.24.6 and earlier are vulnerable to an out-of-bounds read in the MQTT v5 Variable Byte Integer parser, which lacks proper bounds validation when processing 5-byte varints. Remote unauthenticated attackers can trigger a denial of service by sending malformed MQTT packets that crash the broker. No patch is currently available for this vulnerability.
