HIGH 7.2

DescriptionNVD

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.

AnalysisAI

SQL injection in PostgreSQL's pg_createsubscriber utility escalates privileges from pg_create_subscription to superuser, enabling arbitrary SQL execution. Affects PostgreSQL versions 17.0-17.9 and 18.0-18.3; exploitation requires high-privilege access (pg_create_subscription rights) but occurs remotely without additional complexity. …

RemediationAI

Within 24 hours: Audit PostgreSQL deployments to identify versions 17.0-17.9 and 18.0-18.3 and document which accounts hold pg_create_subscription privileges. Within 7 days: Restrict pg_create_subscription role assignment to superuser or highly-vetted accounts only, and implement SQL query monitoring on pg_createsubscriber executions. …
