SigNoz versions from 0.88.0 before 0.142.1 contain a SQL injection vulnerability in trace-funnel analytics endpoints that interpolate service_name and span_name fields into ClickHouse string literals without escaping. Authenticated attackers can inject SQL through funnel step definitions to execute arbitrary queries and read results in HTTP responses.
