EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5% (41st percentile of EPSS-scored CVEs). 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).

A fix is available — apply it.

Incorrect privilege assignment in the ClickHouse connector deployment template in Amazon Athena Federated Query prior to v2026.17.1 could allow an authenticated remote user to read arbitrary AWS Secrets Manager secrets in the deploying account by pointing the connector's connection string at an unrelated secret and at a database endpoint under the user's control, causing the connector to transmit the secret to that endpoint. To remediate this issue, users should upgrade to aws-athena-query-federation connectors version v2026.17.1 or later and ensure that any forked or derivative code is patched to incorporate the new fixes. Alternatively, to remediate this issue, users should redeploy the connector with the current template and supply a non-empty SecretNamePrefix value.
