CVE-2026-53611Network attack vectorHinoki check available

Unauthenticated command execution via partial AS-path validation

Published Sep 2, 2026 · Updated Sep 2, 2026

OS command injection in QuxLabs Looking Glass before 1.3.5 allows remote attackers to execute arbitrary shell commands through BGP lookups. SanitizeASPathRegex accepts a matching numeric substring, then passes trailing shell tokens into a single-quoted internal SSH execution template. Public or otherwise untrusted access to the gRPC/HTTP2 API is sufficient for container compromise and exposure of environment data and backend SSH credentials.
