Upgrade Npgsql to version 4.0.14, 4.1.13, 5.0.18, 6.0.11, 7.0.7, 8.0.3 or higher.
Overview
Npgsql is a .NET data provider for PostgreSQL.
Affected versions of this package are vulnerable to SQL Injection by overflowing the sum of the integer and parameter lengths in NpgsqlConnector.FrontendMessages.cs, allowing arbitrary SQL to be injected into a PostgreSQL protocol message if enough of the relevant parameters can be controlled by the attacker.
