When producing DEDENT tokens, the token builder recomputes line numbers by re-scanning the entire preceding document text. A document whose indentation changes on most lines then takes quadratic time to tokenize. Because tokenization is synchronous, a crafted document of a few hundred kilobytes can block the Node.js event loop for tens of seconds. That causes a DoS for every user served by the same process. Languages built with the DefaultLexer and DefaultTokenBuilder are unaffected.\nhttps://www.cve.org/CVERecord?id=CVE-2026-124683https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/1069https://github.com/eclipse-langium/langium/security/advisories/GHSA-297v-g8mm-qj4hhttps://gitlab.eclipse.org/security/cve-assignment/-/work_items/553#eclipse #EclipseFoundation #EclipseLangium#CVE_2026_124683#bot", "url": "https://infosec.exchange/users/cve/statuses/117587396639706205"}, {"timestamp": "2026-11-09T16:47:35.260Z", "date_only": false, "value": "2026-11-09T16:47:35.260234Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-124683", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-09T16:47:35.260Z", "date_only": false, "value": "2026-11-09T16:47:35.260234Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-124683", "record": "FKIE_CVE-2026-124683", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-09T16:47:45.873Z", "date_only": false, "value": "2026-11-09T16:47:45.873Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-124683", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-09T16:47:45.873Z", "date_only": false, "value": "2026-11-09T16:47:45.873Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-124683", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-09T17:17:27Z", "date_only": false, "value": "2026-11-09T17:17:27Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-MW8J-WQ3M-9899", "record": "GHSA-MW8J-WQ3M-9899", "field": "database_specific.nvd_published_at", "linked_record": true}, {"timestamp": "2026-11-09T17:17:27.690Z", "date_only": false, "value": "2026-11-09T17:17:27.690", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-124683", "record": "FKIE_CVE-2026-124683", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-09T17:17:27.690Z", "date_only": false, "value": "2026-11-09T17:17:27.690", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-124683", "record": "FKIE_CVE-2026-124683", "field": "lastModified", "linked_record": true}, {"timestamp": "2026-11-09T17:19:46.759Z", "date_only": false, "value": "2026-11-09T17:19:46.759589Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/2zbccvh74yx2u", "record": "CVE-2026-124683", "field": "creation_timestamp", "uuid": "b63ee7ad-fe0a-4ad5-83f8-03820a191ed1", "content": "CVE-2026-124683 -
