What it is

Hi.Events is an open-source event management and ticket selling platform. From version 0.8.0-beta.1 to before version 1.7.1-beta, multiple repository classes pass the user-supplied sort_by query parameter directly to Eloquent's orderBy() without validation, enabling SQL injection. The application uses PostgreSQL which supports stacked queries. This issue has been patched in version 1.7.1-beta.
