CVE-2026-34455: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in HiEventsDev Hi.Events
Hi. Events, an open-source event management platform, contains an SQL injection vulnerability in versions from 0. 8. 0-beta. 1 up to but not including 1. 7. 1-beta. The vulnerability arises because user-supplied input in the sort_by query parameter is passed directly to the orderBy() function without validation. This affects multiple repository classes and leverages PostgreSQL's support for stacked queries. The issue has been fixed in version 1.
AI Analysis
Technical Summary
CVE-2026-34455 is an SQL injection vulnerability in Hi.Events versions >= 0.8.0-beta.1 and < 1.7.1-beta. The vulnerability occurs because the application passes the user-controlled sort_by query parameter directly to Eloquent's orderBy() method without proper validation or sanitization. Since PostgreSQL supports stacked queries, this allows an attacker to inject arbitrary SQL commands. The vulnerability has been addressed and patched in version 1.7.1-beta.
Potential Impact
An attacker can exploit this vulnerability to execute arbitrary SQL commands on the backend PostgreSQL database without authentication or user interaction. This can lead to unauthorized data access, data manipulation, or other impacts depending on the database privileges. The CVSS 4.0 base score is 8.7, indicating a high severity vulnerability with network attack vector, no required privileges or user interaction, and high impact on confidentiality.
Mitigation Recommendations
Users and administrators should upgrade Hi.Events to version 1.7.1-beta or later, where this SQL injection vulnerability has been patched. No other mitigations are specified or required once the official fix is applied.
