SQL Injection in PostgreSQL Anonymizer

Publication date: 2026-09-06

Last updated on: 2026-09-06

Assigner: PostgreSQL

Description
PostgreSQL Anonymizer contains a SQL injection vulnerability in two import functions. A user can create a malicious JSON document containing specially crafted object names. If a superuser subsequently calls anon.import_database_rules() or anon.import_roles_rules(), the malicious code is executed with superuser privileges. The issue is fixed in PostgreSQL Anonymizer 3.1.4 and later

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

PostgreSQL Anonymizer has a SQL injection flaw in two import functions. A user can craft a malicious JSON file with specially named objects. If a superuser runs anon.import_database_rules() or anon.import_roles_rules() on this file, the malicious code executes with superuser privileges.

Impact Analysis

An attacker could gain full control of the database server, steal or alter sensitive data, or disrupt operations. Users with superuser access are at highest risk if they import untrusted JSON files.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR or HIPAA requirements for data protection and integrity. Organizations may face compliance penalties if exploited.

Mitigation Strategies

Upgrade PostgreSQL Anonymizer to version 3.1.4 or later to address the SQL injection vulnerability in anon.import_database_rules() and anon.import_roles_rules() functions.
