CVE-2026-113662 — ApostropheCMS import-export: NoSQL injection via update-key value lets a crafted import match and overwrite an unidentified document

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.0 of the import-export module, an authenticated user with import access to a target type can supply an object or operator as an update-key value, causing the import query to match an unidentified existing document that the user has generic edit permission to modify. The normal findForEditing permission filter still limits the candidate documents, so the issue does not permit permission-free overwrite of arbitrary protected content. This issue is fixed in version 3.7.0.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Apostrophecms Apostrophe, Apostrophecms Import-export, Npm @apostrophecms/import-export).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
