Summary

Diesel allows users to configure various options for PostgreSQL's `COPY FROM` and `COPY TO` statements. These configurations are partially provided as strings or characters.

Diesel did not check if any these user-provided options contain a quote character `'`, which can lead to the injection of additional options in the current `COPY FROM`/`COPY TO` statement.

This 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.

## Mitigation

The preferred mitigation to the outlined problem is to update to Diesel version 2.3.8 or newer, which includes fixes for the problem.

## Resolution

Diesel now correctly escapes any quotes contained in the provided arguments.
