  "details": "Diesel allows users to configure various options for PostgreSQL\u0027s `COPY FROM` and `COPY TO` statements. These configurations are partially provided as strings or characters. \n\nDiesel did not check if any these user-provided options contain a quote character `\u0027`, which can lead to the injection of additional options in the current `COPY FROM`/`COPY TO` statement. \n\nThis vulnerability affects any user of `COPY FROM`/`COPY TO` that passes user-provided input to any of the affected functions. It can result in modifications of options in the current statement, but it is not possible inject additional statements.\n\n## Mitigation\n\nThe preferred mitigation to the outlined problem is to update to Diesel version 2.3.8 or newer, which includes fixes for the problem.\n\n## Resolution\n\nDiesel now correctly escapes any quotes contained in the provided arguments.",
