Summary
In the pgx PostgreSQL driver 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 in the SQL query contains text that would be interpreted as a placeholder, and the value of that placeholder is attacker-controlled.
Risk Assessment
Applications using pgx with the simple protocol may be exposed to SQL injection, potentially leading to unauthorized data access or modification.
Recommendation
Upgrade the pgx library to version 5.9.2 or later.
