## What to check

- Applies to: The 27 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR has published an advisory covering multiple vulnerabilities affecting Synology DSM (DiskStation Manager), the operating system used on Synology NAS appliances. The flaws, tracked across 26 CVEs, affect DSM versions 7.2.1.x prior to 7.2.1-69057-13, 7.2.2.x prior to 7.2.2-72806-10, 7.3.x prior to 7.3.2-86009-5, and 7.4.1.x prior to 7.4.1-90080-1. Exploitation of the issues could allow an attacker to cause a remote denial of service, compromise the confidentiality of data on the device, bypass security controls, or trigger server-side request forgery (SSRF).

The advisory references two Synology security bulletins (SA_26_18 and SA_26_19) published 10 November 2026 as the authoritative sources for patch details. No evidence of in-the-wild exploitation is mentioned in the advisory. Defenders operating Synology DSM should prioritize upgrading to the fixed builds referenced above and monitor Synology's own bulletins for any updates on exploitation status or additional affected products.
