SQL Injection via placeholder confusion with dollar quoted string literals in github.com/jackc/pgx
SQL Injection can occur when using the non-default simple protocol with a dollar quoted string literal in the SQL query. If that string literal contains text that would be interpreted as a placeholder outside of a string literal, and the value of that placeholder is controllable by the attacker, an injection may be possible.
For example, an attacker could provide a value that includes a closing dollar quote followed by malicious SQL commands. This is unlikely to occur outside of a contrived scenario.
