CVE-2026-57955Public exploitNetwork attack vector

Authenticated SQL injection via unvalidated rule ID

Published Jun 29, 2026 · Updated Jun 29, 2026

SQL injection in SigNoz 0.130.1 and earlier allows remote authenticated users to execute arbitrary ClickHouse queries via a crafted rule ID. The alert-history handlers pass the decoded ID to ClickHouse reader functions that insert it into SQL with fmt.Sprintf, without UUID validation or parameterization. Viewer access is sufficient to read stored traces, logs, and metrics or make server-side requests when ClickHouse has outbound network access.
