AWS Expands Babelfish Privilege-Escalation Remediation
Tech GuruQuick Answer
Inventory Babelfish extensions and Aurora PostgreSQL clusters with Babelfish enabled. Apply the exact branch-specific update and pending maintenance; validate database connectivity and permissions, retaining engine and extension-version evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Record standalone extension versions, Aurora engine and embedded Babelfish versions, enabled TDS access, database roles, forks and pending maintenance. Match the documented versions and feature prerequisites to the deployment. Standalone Babelfish 1.2–1.5, 2.1–2.15, 3.1–3.12, 4.0–4.8 and 5.1–5.4; Aurora uses the separate engine and embedded-version matrix in the linked bulletin. Upgrade standalone Babelfish to 4.10, 5.6 or 6.1 on the supported branch. For Aurora, select the exact engine patch mapped in the bulletin and apply pending maintenance. Patch derivative code; AWS lists no workaround. Verify engine and extension versions, test TDS application logins and database role boundaries, and retain maintenance completion and regression-test evidence.

Authority-Specific Scope And Version Evidence
| Scope and action | AWS expands the supported Aurora PostgreSQL patch mapping for the Babelfish privilege-escalation flaw; standalone extensions and managed clusters need different version targets. |
|---|---|
| Date basis | 2026-11-03 18:00:00 UTC |
| Engine mapping | Use the full branch-specific Aurora mapping in 2026-165-AWS. Examples include 13.23.3 (Babelfish 1.17.2), 14.23.1 (2.17.0), 15.18.1 (3.14.0), 16.14.1 (4.10.0), 17.10.1 (5.6.0) and 18.4.1 (6.1.0); earlier supported branches have separate minimum patch builds. |
What Changed
AWS expands the supported Aurora PostgreSQL patch mapping for the Babelfish privilege-escalation flaw; standalone extensions and managed clusters need different version targets.
What To Validate Now
- Inventory. Record standalone extension versions, Aurora engine and embedded Babelfish versions, enabled TDS access, database roles, forks and pending maintenance.
- Establish applicability. Match the documented versions and feature prerequisites to the deployment. Standalone Babelfish 1.2–1.5, 2.1–2.15, 3.1–3.12, 4.0–4.8 and 5.1–5.4; Aurora uses the separate engine and embedded-version matrix in the linked bulletin.
- Remediate. Upgrade standalone Babelfish to 4.10, 5.6 or 6.1 on the supported branch. For Aurora, select the exact engine patch mapped in the bulletin and apply pending maintenance. Patch derivative code; AWS lists no workaround.
- Validate. Verify engine and extension versions, test TDS application logins and database role boundaries, and retain maintenance completion and regression-test evidence.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Aurora engine and embedded Babelfish versions have separate mappings; do not substitute a standalone extension version for an Aurora engine target.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
