    "title": "ApostropheCMS import-export: NoSQL injection via update-key value lets a crafted import match and overwrite an unidentified document",
    "summary": "## Summary `@apostrophecms/import-export`'s update-by-key feature lets an imported document carry a `:key` property (for example `slug:key`) whose value is used to find an existing document to update instead of inserting a new one. `getUpdateKey()`/`insertOrUpdateDocWithKey()` (`lib/methods/import.js`) use that value directly as a MongoDB query value with no laundering: ```js const matchingDraftPromise = manager.findForEditing( req.clone({ mode: 'draft' }), { aposMode: 'draft', [updateField]: doc[updateKey] }).toObject(); ``` Archive documents are parsed with EJSON (see `lib/formats/gzip.js`), which revives objects such as `{ $ne: null }` as live values, the same untrusted data source and revival mechanism already fixed once in this module for `findSingletonAposDocId`/`findParkedAposDocId` in GHSA-79qf-vqgc-7xx3. That fix did not touch `insertOrUpdateDocWithKey`, so the identical class of bug survives here: a crafted `\"slug:key\": { \"$ne\": null }` entry in an archive's `aposDocs.json` makes the import match (and then update) an existing document the archive's author never actually identified, instead of failing to find a match. ## Impact Reaching this requires only an authenticated session with import access to the target type (the built-in contributor role holds this, matching the precondition of GHSA-79qf-vqgc-7xx3), and no admin interaction. Because the match uses a MongoDB operator instead of an exact value, it is not limited to a document the importer already knows the id",
