MediumCVSS 5.3Summary
Malicious HTML content could be injected into the email address of an order, which pretix showed without sanitization on the confirmation page for individual tickets in that order.
Risk Assessment
An attacker could exploit this vulnerability to perform a cross-site scripting (XSS) attack, potentially leading to session theft or display of fraudulent content.
Recommendation
Update pretix to the latest version that includes a fix for the missing input sanitization in the email address field.

Malicious HTML content could be injected into the page pretix shows when redirection to an untrusted page occurs. Since this page has a Content-Security-Policy, this can mainly be used for phishing purposes.
- CVE-2026-13602High
A chain of vulnerabilities was found in pretix: payment plugins (Stripe, Mollie, OPPWA, BitPay, Payone, SecuConnect, Sofort, Saferpay) do not validate session parameters beyond cryptographic signature, the redirect feature uses the same key and salt for signing as the plugins, and the admin impersonation feature allows changing user after injecting arbitrary parameters. An attacker with access to at least one event can become any backend user and access all data.
- CVE-2026-5600Medium
Pretix 2025 introduces a new API endpoint that returns check-in data for all events of an organizer instead of a specific event. This allows unauthorized users to access check-in information for other events.
