CVE-2026-6472: Missing Authorization in PostgreSQL
Missing authorization in PostgreSQL CREATE TYPE allows an object creator to hijack other queries that use search_path to find user-defined types, including extension-defined types. That is to say, the victim will execute arbitrary SQL functions of the attacker's choice. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.
AI Analysis
Technical Summary
This vulnerability arises from missing authorization in the PostgreSQL CREATE TYPE functionality. An attacker able to create types can manipulate the search_path resolution mechanism to cause victim queries to execute arbitrary SQL functions controlled by the attacker. Affected versions include PostgreSQL releases before 18.4, 17.10, 16.14, 15.18, and 14.23. The CVSS 3.1 base score is 5.4, indicating a medium severity with network attack vector, low attack complexity, requiring privileges, no user interaction, and impacting confidentiality and integrity.
Potential Impact
An attacker with the ability to create types in PostgreSQL can hijack other queries that use search_path to find user-defined types, potentially causing those queries to execute arbitrary SQL functions chosen by the attacker. This can lead to unauthorized information disclosure and modification of data integrity. There is no indication of availability impact. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the official PostgreSQL vendor advisory for current remediation guidance. Until a patch or official fix is available, restrict CREATE TYPE privileges to trusted users only to reduce risk.
