CVE-2026-60118

Hi.Events < 1.11.0 Hidden Ticket Enumeration via Order Creation Endpoint

Published Jul 14, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
Hi.Events before 1.11.0 contains a missing server-side visibility enforcement vulnerability that allows unauthenticated attackers to purchase hidden tickets by referencing hidden product and price IDs in order creation requests without authorization checks. Attackers can enumerate sequential hidden ticket IDs from visible ones and submit order creation requests referencing those IDs to purchase VIP, invite-only, or discounted tickets intentionally withheld from public sale.

Analysis

AI-generated

Technical impact

Hi.Events versions before 1.11.0 omit server‑side visibility checks, letting an attacker send order creation requests that reference hidden product and price identifiers. Because no authentication or authorization is performed, the attacker can buy tickets that are meant to remain private, such as VIP, invite‑only, or heavily discounted items, leading to revenue loss and potential misuse of premium access. The flaw maps to Missing Authorization (CWE‑862).

Affected Systems

The vulnerability affects all instances of Hi.Events deployed with a version older than 1.11.0, including the beta and release candidates preceding that milestone. The issue is active against the order creation API endpoint exposed by the Hi.Events application.

Risk and Exploitability

The CVSS score of 6.9 grades the issue as moderate, while the EPSS score of less than 1% indicates a very low likelihood of real‑world exploitation at the present moment. The flaw is not listed in the CISA KEV catalog. Attackers would exploit the defect by sending crafted POST requests to the order creation endpoint without needing any credentials; enumeration of sequential hidden ticket IDs is trivial once a valid hidden ID is discovered.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the Hi.Events application to version 1.11.0 or later, which implements proper server‑side visibility enforcement on the order creation endpoint.
  • If an upgrade is not immediately possible, enforce authentication or API‑key validation on the order creation endpoint so that only authorized requests can reference hidden product identifiers.
  • As a temporary measure, implement network‑level restrictions or rate limiting on the order creation API to avoid automated enumeration attempts.
