CVE-2026-92729
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.
