Subject: pgsql: Fix SQL injection in logical replication origin checks.
Date: Mon, 11 May 2026 12:19:37 +0000
Message-ID: <[email protected]> (raw)
Fix SQL injection in logical replication origin checks.
ALTER SUBSCRIPTION ... REFRESH PUBLICATION interpolates schema and
relation names into SQL without quoting them. A crafted subscriber
relation name can inject arbitrary SQL on the publisher. Test such a
name. Back-patch to v16, where commit
875693019053b8897ec3983e292acbb439b088c3 first appeared.
