CVE-2026-15741: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in PostgreSQL
CVE-2026-15741 is a high-severity SQL injection vulnerability in PostgreSQL's EXTRACT() deparse functionality. It allows an object owner to execute arbitrary SQL commands with superuser privileges via a malicious object definition. This affects various tools that consume expression deparses, including pg_dump and psql commands like \sf. Versions prior to PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are vulnerable.
AI Analysis
Technical Summary
This vulnerability involves improper neutralization of special elements used in SQL commands within PostgreSQL's EXTRACT() deparse. An attacker who owns an object can craft a hostile object definition that leads to execution of arbitrary SQL commands as a superuser. The flaw impacts expression deparse consumers broadly, including core tools such as pg_dump and psql's \sf command, as well as similar non-core tools. The vulnerability affects PostgreSQL versions before 18.6, 17.11, 16.15, 15.19, and 14.24.
Potential Impact
Successful exploitation allows an object owner to execute arbitrary SQL commands with superuser privileges, potentially leading to full system compromise, data disclosure, and data manipulation. The vulnerability affects multiple PostgreSQL versions and tools that rely on expression deparse, increasing the attack surface.
Mitigation Recommendations
A fix is available in PostgreSQL versions 18.6, 17.11, 16.15, 15.19, and 14.24 and later. Users should upgrade to these or later versions to remediate the vulnerability. No additional mitigation guidance is provided in the input data.
