CVE-2026-78799Network attack vector

Authenticated code execution via file-path traversal

Published Oct 13, 2026 · Updated Oct 13, 2026

Path traversal in IK-Q3000 allows remote authenticated users to execute arbitrary code via manipulated file-path parameters. File-path handling insufficiently validates user-controlled paths, allowing access outside the intended directory; the affected endpoint and execution chain are not disclosed. The disclosure covers Enterprise Edition 3.7.23 build 202606021825 and earlier and Free Edition 4.0.304-beta and earlier, with authentication required but account permissions unspecified.
