CVE-2026-75910 is a high-severity Incorrect Privilege Assignment (CWE-266) vulnerability in Amazon Athena Federated (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and AC-2 (Account Management) — see the control section below for these in your framework.

Vulnerability Data
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…
more
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.

Mitigating Controls (NIST 800-53 r5) AI
Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.
Account management defines and authorizes the exact privileges granted to each account or role.
Enforces only the authorizations that were assigned, so correct assignment is a prerequisite.
Separation of duties constrains which privilege combinations may be assigned to any actor.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.
Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.
Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.
Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.
Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.
Information-access-restriction mechanisms enforce the correct privilege boundaries once assignment rules are defined.
