AWS Athena Synapse Connector Vulnerability Requires Immediate Patching
AWS Athena's Synapse connector has a critical flaw (CVE-2026-12283) where specially crafted table names can leak unintended data when queried. If you're running versions v2022.20.1 through v2026.19.1, you need to update immediately—this affects anyone using Athena Query Federation with Azure Synapse. The vulnerability requires attacker access to your Synapse account, but the impact is serious enough that AWS flagged it as Important.
