Description OSIDB Bzimport 2026-05-14 14:01:36 UTC 
SQL injection in PostgreSQL pg_createsubscriber allows an attacker with pg_create_subscription rights to execute arbitrary SQL as a superuser.  The attack takes effect when pg_createsubscriber next runs.  Within major versions 17 and 18, minor versions before PostgreSQL 18.4 and 17.10 are affected.  Versions before PostgreSQL 17 are unaffected.
