Prior to 2.37.0, the ADD_CALENDAR handler in defaultmodules/calendar/node_helper.js accepts an attacker-controlled URL, authentication data, and selfSignedCert setting through the unauthenticated Socket.IO namespace /calendar. The handler passes these fields to CalendarFetcher, causing a server-side request without SSRF validation and optionally disabling TLS verification. When the response is valid iCal, CALENDAR_EVENTS returns parsed event data to the attacker, allowing internal-service response data to be exfiltrated; other responses still provide a blind request and timing primitive. This issue is fixed in version 2.37.0."}],"source":{"advisory":"GHSA-w6x9-28jw-hq7j","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-19T18:04:16.917040Z","id":"CVE-2026-63643","options":[{"Exploitation":"none"},{"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":"2026-08-19T18:21:37.126Z"}}]}}
