This follow-up is a static remediation review. We have not repeated the original end-to-end reproductions against the latest release or tested a deployed site. Current exploitability and impact therefore still require maintainer validation; the observations below establish that the reported security checks remain absent in public source. The original emailed PDF contains the original reproduction material. Please refer to that existing private attachment.\n\n## Archive duplicate continuation permits unauthorized published-content replacement\n\nThe overrideDuplicates() continuation still accepts client-supplied replacement choices, rather than binding them to a server-maintained, user-owned duplicate analysis. The replacement and write helpers do not establish a single canonical resource identity and authorization context before the update. This leaves the reported gap between draft editing authority and the published target selected for replacement unresolved at source level.\n\nThe original report describes a contributor crossing the publication boundary through duplicate replacement on an import-enabled localized type. We have not repeated that end-to-end sequence on 3.7.0.\n\nSuggested remediation: bind continuation state to the initiating user, archive, job, permitted source/target mapping, locale and mode; reject inconsistent identity metadata; derive permissions from the actual loaded target and require publication authority for published targets.\n\nSource: overrideDuplicates(), replaceDocId(), and insertOrUpdateDoc() in the [importer](https://github.com/apostrophecms/apostrophe/blob/5ce3732be0ebdebb4db0f8ef160c81e8671157e6/packages/import-export/lib/methods/import.js).\n\n## Coordination\n\nVivek R / Winfunc\nOriginal reporting team: Mufeed VH / Winfunc","state":0,"publishedAt":"2026-10-21T16:59:19+00:00","modifiedAt":"2026-10-21T17:15:08.632339+00:00","affected":[{"ecosystem":"npm","name":"@apostrophecms/import-export","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"3.7.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-jf5h-36mg-rp6x","https://nvd.nist.gov/vuln/detail/CVE-2026-112956","https://github.com/apostrophecms/apostrophe/commit/06e4b377f3c360f9e89c32dccd7e505ad5ddf498","https://github.com/apostrophecms/apostrophe/commit/40b989b1a9dd23d30029b8ce7668634265cfe5ea","https://github.com/apostrophecms/apostrophe","https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/import-export@3.7.1"],"sourceUrl":"https://github.com/advisories/GHSA-jf5h-36mg-rp6x","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-jf5h-36mg-rp6x","identifiers":["GHSA-jf5h-36mg-rp6x","CVE-2026-112956"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
