6DescriptionNVD
pgx is a PostgreSQL driver and toolkit for Go. Prior to version 5.9.2, SQL injection can occur when the non-default simple protocol is used, a dollar quoted string literal is used in the SQL query, that string literal contains text that would be would be interpreted as a placeholder outside of a string literal, and the value of that placeholder is controllable by the attacker. This issue has been patched in version 5.9.2.
AnalysisAI
SQL injection vulnerability in pgx (Go PostgreSQL driver) prior to version 5.9.2 allows authenticated attackers to manipulate queries when the non-default simple protocol is used in conjunction with dollar-quoted string literals containing attacker-controlled placeholder-like text. The vulnerability requires specific configuration (simple protocol mode enabled) and precise SQL structure (dollar-quoted strings with embedded placeholder syntax), making exploitation unlikely in typical deployments but possible in applications explicitly using QueryExecModeSimpleProtocol.
