Superuser SQL execution via crafted queue messages
Published Jul 28, 2026 · Updated Jul 28, 2026
SQL injection in EnterpriseDB pglogical 2.x before 2.4.8 allows remote authenticated users to execute arbitrary SQL as superuser. The queue mechanism treats a publisher-supplied message payload, including replicated DDL, as SQL and runs it in the subscriber's apply worker without constraining it to the publisher's role. Exploitation requires control of a publisher endpoint and permission to direct a subscription to it; default installations reserve that permission for superusers, while delegated managed deployments expose the escalation path.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
