Descripción
*** Pendiente de traducción *** SigNoz versions 0.87.0 before 0.142.0 fail to escape user-supplied telemetry field-key names in the v5 query_range API, allowing authenticated users to inject SQL. Attackers with Viewer role or higher can embed backticks and quotes in field names to break out of identifiers and string literals, executing arbitrary ClickHouse SQL to read system tables and exfiltrate data.
