CVE-2026-34455Public exploitNetwork attack vector

Authenticated SQL injection via unvalidated sort parameter

Published Apr 1, 2026 · Updated Apr 1, 2026

SQL injection in Hi.Events 0.8.0-beta.1 through 1.7.0-beta allows remote authenticated users to execute SQL via sort_by. AttendeeRepository.php and more than ten other repository classes pass the parameter directly to Eloquent orderBy() without applying the existing allowed-sort whitelist. An organizer account is required; PostgreSQL stacked queries expose attendee PII, payment data, and promo codes to database reads.
