• CVE-2026-113662: 0.30% estimated exploitation activity in the next 30 days; percentile 22.85 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary @apostrophecms/import-export's update-by-key feature lets an imported document carry a <field: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: 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…

# Patch Next advisory brief: CVE-2026-113662

Advisory: ApostropheCMS import-export: NoSQL injection via update-key value lets a crafted import match and overwrite an unidentified document
IDs: CVE-2026-113662, GHSA-jqw5-w6h3-44g6
Record: https://patchnext.com/advisories/cve-2026-113662 (revision 3, source checked 26 Oct 2026, 13:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @apostrophecms/import-export 3.7.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @apostrophecms/import-export: affected < 3.7.0; fixed in 3.7.0

## Suggested inspection (read-only)
- `npm ls @apostrophecms/import-export --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @apostrophecms/import-export.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-jqw5-w6h3-44g6 (GitHub-reviewed advisory GHSA-jqw5-w6h3-44g6 lists affected ranges: npm @apostrophecms/import-export >=0 <3.7.0)
- Verified: https://osv.dev/vulnerability/GHSA-jqw5-w6h3-44g6 (OSV record GHSA-jqw5-w6h3-44g6 lists affected ranges: npm @apostrophecms/import-export >=0 <3.7.0 (fixed))
