{"id":"CVE-2026-95845","published":"2026-09-23T17:17:21.470","lastModified":"2026-09-25T13:34:37.383","description":"Moquette is a lightweight Java MQTT broker. 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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-770"],"vendors":["moquette"],"products":["moquette"],"references":[{"url":"https://github.com/moquette-io/moquette/commit/2482cadfba44e615be704b892009a57ce06a1aba","tags":["Patch"]},{"url":"https://github.com/moquette-io/moquette/releases/tag/v0.18.1","tags":["Release Notes"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]}],"exploitRefs":[{"url":"https://github.com/moquette-io/moquette/commit/2482cadfba44e615be704b892009a57ce06a1aba","tags":["Patch"]},{"url":"https://github.com/moquette-io/moquette/releases/tag/v0.18.1","tags":["Release Notes"]},{"url":"https://github.com/moquette-io/moquette/security/advisories/GHSA-5f42-97gr-vfhq","tags":["Exploit","Mitigation","Vendor Advisory"]}],"hasPoc":true,"ai":null}
