Description

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.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

0.8.0 ≤ v < 1.7.1
0.8.0-beta.1 ≤ v < 1.7.1-beta
Affected range stops below 1.7.1-beta, so it looks safe — our inference, not a vendor statement
