HIGHPre-NVD 8.28.2—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 56% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
