CVE-2026-50165: CWE-284: Improper Access Control in alfio-event alf.io
CVE-2026-50165 is an improper access control vulnerability in alf.io, an open source ticket reservation system. Versions prior to 2.0-M5-2605 allow organization owners to access system-level configuration secrets via certain endpoints intended for organization or event scoped configurations. This includes sensitive data such as the system API key. The issue is fixed in version 2.0-M5-2605.
AI Analysis
Technical Summary
alf.io versions before 2.0-M5-2605 contain an improper access control flaw (CWE-284) where organization or event owners can retrieve system-level secrets through 'single configuration' endpoints. These endpoints accept arbitrary configuration keys and return the first matching value from a lookup that includes system-level configurations, exposing administrator-only secrets like the system API key. The vulnerability has a CVSS 4.0 score of 7.1 (high severity) and is addressed by updating to version 2.0-M5-2605.
Potential Impact
An attacker with organization owner privileges can access sensitive system-level configuration secrets that should be restricted to administrators. This may lead to unauthorized disclosure of critical secrets such as the system API key, potentially compromising the integrity and security of the system.
Mitigation Recommendations
Upgrade alf.io to version 2.0-M5-2605 or later, where this access control issue is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the vendor advisory, but the description states the issue is fixed in 2.0-M5-2605.
