Background
The PostgreSQL JDBC driver is a Java library that allows applications to connect to and interact with PostgreSQL databases. It provides a set of classes and methods for executing SQL statements, managing database connections, and handling result sets. The driver is commonly used in Java applications that need to access PostgreSQL databases. However, versions before 8.2 of the driver are vulnerable to a SQL injection attack when used with a PostgreSQL server with the "standard_conforming_strings" option enabled.
Vulnerability Detail
The vulnerability arises from an interaction error in the PostgreSQL JDBC driver. When used with a PostgreSQL server that has the "standard_conforming_strings" option enabled, the driver fails to properly escape unspecified JDBC statement parameters. This allows remote attackers to perform SQL injection attacks, potentially leading to unauthorized access, data manipulation, or other malicious activities. The issue was first reported in 2012 and remains unresolved as of 2023.
How To Fix
Latest published version: 42.7.14 as of 22 Oct 2026

Workaround
If upgrading to a newer version of the PostgreSQL JDBC driver is not immediately feasible, a possible workaround is to disable the "standard_conforming_strings" option in the PostgreSQL server configuration. This can be done by modifying the PostgreSQL server's configuration file and setting the "standard_conforming_strings" option to 'off'. However, this workaround may have other implications and should be carefully evaluated before implementation.
Conclusion
The PostgreSQL JDBC driver before version 8.2 is vulnerable to SQL injection attacks when used with a PostgreSQL server with the "standard_conforming_strings" option enabled. To mitigate this vulnerability, it is recommended to upgrade to a version of the driver that is 8.2 or later. Alternatively, disabling the "standard_conforming_strings" option in the PostgreSQL server configuration can serve as a temporary workaround.
