Prior to 0.18.1, the broker does not enforce a maximum length for pending per-session message queues. When a fast publisher sends messages to a slow subscriber whose in-flight window is full, queued messages can accumulate without bound in memory or persistent storage. Remote clients can use this condition to exhaust broker resources and cause a denial of service. This issue is fixed in version 0.18.1.\n\n## Affected\n\n- `moquette < 0.18.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `moquette 0.18.1`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":210853,"id":"CVE-2026-95845","ts":1790345424333,"field":"cvss","old":"8.7","new":"7.5"}]}
