Title
SigNoz 0.88.0 through 0.141.0 - Missing Authentication on Trace Funnel Analytics Endpoints
Summary
SigNoz versions 0.88.0 through 0.141.0 fail to apply authorization wrappers to trace-funnel analytics endpoints in the HTTP handler. Unauthenticated attackers can submit arbitrary funnel definitions to retrieve trace analytics including identifiers, durations, span counts, service topology, and error activity without credentials.
