Npgsql is vulnerable to SQL injection. The vulnerability is caused by an integer overflow in the WriteBind() method within NpgsqlConnector.FrontendMessages.cs, which leads to miscalculated message lengths when constructing PostgreSQL protocol messages. This allows attackers to manipulate message boundaries and potentially inject arbitrary SQL statements.
