CVE-2026-63252: Eclipse Milo

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

In Eclipse Milo versions 0.6.0 through 1.1.4, UASC server transport handlers fail to release retained partial message chunks when a channel disconnects, allowing a remote unauthenticated client to exhaust pooled direct memory by repeatedly sending incomplete chunks and disconnecting, potentially terminating the server.

Affected products

• Eclipse Milo: from 0.6.0, before 1.1.5 (fixed in 1.1.5)
