SQL injection in PostgreSQL EXTRACT() deparse allows an object owner to execute arbitrary SQL as a superuser via a hostile object definition. (CVE-2026-15741)
A SQL injection vulnerability exists in the PostgreSQL EXTRACT() function deparse process that allows an object owner to execute arbitrary SQL commands with superuser privileges via a malicious object definition. This affects tools and commands that consume expression deparse output, including pg_dump and psql commands like \sf. Versions prior to PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are impacted.
AI Analysis
Technical Summary
CVE-2026-15741 is a SQL injection vulnerability in PostgreSQL's EXTRACT() function deparse mechanism. An attacker who owns a database object can craft a hostile object definition that results in arbitrary SQL execution with superuser privileges. This vulnerability affects expression deparse consumers broadly, including core tools such as pg_dump and psql commands like \sf, as well as similar non-core tools. The vulnerability impacts PostgreSQL versions before 18.5, 17.11, 16.15, 15.19, and 14.24.
Potential Impact
Successful exploitation allows an object owner to execute arbitrary SQL commands as a superuser, potentially leading to full system compromise, data disclosure, data modification, or denial of service. The vulnerability affects multiple PostgreSQL versions and impacts widely used database tools that rely on expression deparse, increasing the risk of privilege escalation and unauthorized actions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor PostgreSQL vendor advisories for official patches or updates addressing this vulnerability. Until a patch is available, restrict object creation privileges to trusted users only to reduce risk.
