CVE-2026-17569Network attack vector

Stored API token disclosure via partial endpoint

Published Jul 27, 2026 · Updated Jul 27, 2026

Improper access control in Devolutions Server allows remote authenticated users to disclose a stored NetBox API token. The NetBox synchronizer's partial connection endpoint returns the saved token without enforcing permission to view the secret. View-only entry permission is sufficient in 2026.1.23.0 and earlier and 2026.2.4.0 through 2026.2.12.0; no server-data modification is reported.
