CVE-2026-18028: Pretix GmbH Pretix

Low severity, CVSS 2.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Pretix GmbH Pretix: before 2026.4.6 (fixed in 2026.4.6); from 2026.5.0, before 2026.5.4 (fixed in 2026.5.4); from 2026.6.0, before 2026.6.1 (fixed in 2026.6.1)
