CVE-2026-113652 · Severity: medium · CVSS 5.6 · Published 2026-10-20

ApostropheCMS is an open-source Node.js content management system that manages website content and files. When configured to store uploads on Microsoft Azure, a vulnerability exposes the account-level SAS token—a credential that grants broad access to cloud storage—in every public attachment URL. An attacker who obtains these URLs can access or modify all files stored in the Azure account.

Technologies: ApostropheCMS Apostrophe. Vendors: ApostropheCMS, npm.

How to fix

uploadfs (npm): upgrade to 1.28.0 or later
```
npm install uploadfs@1.28.0
```

Technical details

The uploadfs Azure backend embeds a full SAS query string into the BlobServiceClient URL during container creation, and Azure SDK v12 derived clients inherit that query string, causing it to appear in every public attachment URL. This affects versions 1.25.0 through 1.28.0 when uploadfs is configured with the Azure backend and sas: true. An unauthenticated attacker with knowledge of a public attachment URL gains the account-level SAS token and can perform operations permitted by that token.

Affected products
