## Technical details

The vulnerability is a SQL injection flaw in SigNoz's trace-funnel analytics endpoints that construct ClickHouse queries by directly interpolating service_name and span_name fields into string literals without proper escaping. Authenticated users can inject arbitrary SQL via funnel step definitions to execute queries against the ClickHouse backend and receive results in HTTP responses. The vulnerability affects versions 0.88.0 through 0.142.0, with a fix available in version 0.142.1. This is a server-side injection requiring authentication, allowing attackers with legitimate access to escalate privileges and read arbitrary data from the analytics database.
