Prior to version 0.9.0, the custom CappedConcurrentHashMap introduced for Java TLS state tracking never removes keys from its insertion-order queue when entries are deleted. In long-running instrumented JVMs, repeated connection churn can therefore grow the queue without bound and exhaust heap memory. This issue has been patched in version 0.9.0."}],"source":{"advisory":"GHSA-962q-hwm5-52x5","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-962q-hwm5-52x5","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-02T17:19:08.840062Z","id":"CVE-2026-45682","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-02T17:20:47.453Z"}}]}}
