CVE-2026-12045Public exploitNetwork attack vector

Arbitrary SQL via read-only transaction escape

Published Jun 18, 2026 · Updated Jun 18, 2026

SQL injection in pgAdmin 4 9.13 through 9.15 allows remote authenticated users to execute arbitrary SQL through the AI Assistant. The execute_sql_query tool passes LLM-generated multi-statement text to the database, so a leading COMMIT escapes its read-only transaction and later statements run in autocommit mode. An attacker must plant prompt-injection content in data the assistant reads; writes inherit the connected role, and superuser roles enable host command execution.
