Vulnerability from github – Published: 2026-07-28 12:31 – Updated: 2026-07-28 12:31

Details

The "quick setup" view presented to users after they first create an event allows to set up the most critical parts of an event in just a few clicks. This view did not properly check that the user has permission to change configuration for the given event. An attacker could use a well-timed request to create products, quotas, set bank transfer configuration, or connect a stripe account to an event they do not have access to.

Severity

2.3 (Low)
