Prior to 3.7.1 of the import-export module, duplicate-import continuation accepts client-controlled replacement choices without binding them to a user-owned server-side analysis or authorizing the canonical target. On an import-enabled localized type, a contributor with draft editing authority can cross the publication boundary by selecting a published document for replacement, although the current assessment is based on remediation review rather than a repeated end-to-end reproduction. This issue is fixed in version 3.7.1."}],"source":{"advisory":"GHSA-jf5h-36mg-rp6x","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-20T16:14:45.468268Z","id":"CVE-2026-112956","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":"2026-10-20T16:15:02.976Z"}}]}}
