CVE-2026-51992 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. ClickHouse's PostgreSQL integration intentionally allows users with valid PostgreSQL credentials to execute queries against a remote PostgreSQL server. No vulnerability in ClickHouse is exploited; code execution occurs on the downstream PostgreSQL server using credentials explicitly provided by the user with specific pg_execute_server_program permission, exploiting a feature that was wrongly reported as CVE-2019-9193 in PostgreSQL (https://www.postgresql.org/about/news/cve-2019-9193-not-a-security-vulnerability-1935/).
A SQL injection vulnerability has been identified in ClickHouse Server versions through 26.3.9.8. This vulnerability allows remote attackers to execute arbitrary code by exploiting the 'create dictionaries' function. The issue arises because PostgreSQL dictionaries created in ClickHouse can be manipulated to execute unauthorized SQL commands, which may lead to executing arbitrary commands on the database server.
