EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 53% 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).

SQL injection in ClickHouse-backed meter definitions in OpenMeter OpenMeter before v1.0.0-beta.228 on all platforms allows a remote unauthenticated attacker to access or modify metering event data, and potentially cause denial of service, via crafted user-controlled JSONPath values submitted to meters API.
