ApostropheCMS: Import API bypasses publication roles for protected content

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module and 4.34.0 of core ApostropheCMS, an editor who can import an enabled content type but lacks its stronger publication role can cause import write helpers to create, replace, or remove published variants without the normal publish permission and lifecycle checks. This issue is fixed in import-export 3.7.1 and ApostropheCMS 4.34.0.

## Review scope and evidence limits Package: @apostrophecms/import-export, version 3.7.0. Release tag reviewed: @apostrophecms/[email protected], commit 9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce (September 30, 2026). Current main reviewed: 5ce3732be0ebdebb4db0f8ef160c81e8671157e6. The importer, gzip extractor, import permission gate, and core permission implementation have no differences between that release tag and the reviewed main. 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. ## Import API bypasses publication roles for protected content The import gate in canImportOrExport() checks the type's import configuration and view permission. The write helpers then call document-manager insert/update directly, including operations on published variants. We did not find the normal publish permission check or beforePublish transition in these helpers. Core permissions intentionally distinguish editRole and publishRole, and the ordinary publication lifecycle enforces that distinction. The reported security boundary is a content type that an editor may edit but whose publication is reserved for a stronger role. Direct public-state changes through import must enforce the same publication authority. The original report describes unauthorized creation, replacement, or removal of published content under that configuration. Suggested remediation: centralize authorization for import writes; require publish permission for every non-autopublished published variant, authorize each concrete target, and preflight the complete import before persistent changes. Preserve authorized draft imports and the intended behavior of autopublished types.
