CVE-2026-61387 - Eclipse Milo Monitored-Item Quota Exhaustion Denial of Service
CVE ID :CVE-2026-61387
Published : Aug. 4, 2026, 11:52 a.m. | 1 hour, 2 minutes ago
Description :In Eclipse Milo versions 1.0.0 through 1.1.4, monitored-item quota accounting is not exception-safe: if item creation fails with an unchecked error, the server-global reservation is not restored. Deeply nested PubSub ExtensionObjects in a `CreateMonitoredItems` event filter can trigger a `StackOverflowError` during decoding, allowing an unauthenticated remote client to exhaust a finite global monitored-item quota and prevent all clients from creating new monitored items until restart. Existing monitored items and other server functions remain unaffected.
Severity: 6.9 | MEDIUM
