CVE-2026-50165 Details
Description
alf.io is an open source ticket reservation system for conferences, trade shows, workshops, and meetups. An Improper Access Control issue in versions prior to 2.0-M5-2605 allows an organization owner to read system-level configuration secrets through organization/event scoped "single configuration" endpoints. The affected endpoints require organization or event ownership, but they accept an arbitrary configuration key and then return the first matching value from a lookup that includes system-level configuration. As a result, an organization owner can retrieve secrets intended to be administrator-only, including the system API key when it is configured. Version 2.0-M5-2605 fixes the issue.
A vulnerability in alf.io versions prior to 2.0-M5-2605 allows organization owners to access system-level configuration secrets through organization or event-specific 'single configuration' endpoints. These endpoints, while requiring ownership, accept arbitrary configuration keys and return the first matching value from a lookup that includes sensitive system-level information. This flaw enables organization owners to retrieve administrator-only secrets, such as the system API key, when it is set. The vulnerability arises from improper access control, allowing unauthorized access to sensitive data.
Users can upgrade to alf.io version 2.0-M5-2606 or later to address this vulnerability.
