CVE-2026-16471Network attack vector

Unauthorized data access

Published Aug 17, 2026 · Updated Aug 17, 2026

Broken access control in Dolusoft Sonlogger before 6.7.4.8 allows remote attackers to read data via unspecified network requests. TR-CERT and the public advisory describe the issue only as missing authorization for functionality constrained by ACLs and do not identify the affected endpoint, module, or authorization check. Exposure depends on network reachability of the Sonlogger management interface, and the published scoring indicates that no prior authentication or user interaction is required; the documented impact is limited to unauthorized data access.
