CVE-2026-13602
Overview
CVE-2026-13602 is a known-severity vulnerability. It was published on July 1, 2026.
Technical Description
We found a chain of combining multiple weaknesses in the product that could allow an attacker to become any user in the backend and access any data:
*
The payment integration plugins Stripe (included in the core system), pretix-mollie, pretix-oppwa, pretix-bitpay, pretix-payone, pretix-secuconnect, pretix-sofort, and pretix-saferpay
contain a code path that is intended for the transport of session
parameters from a tab with isolated cookies (e.g. in the pretix widget)
to a new tab. For this purpose, a set of session parameters is
cryptographically signed and then passed to the new tab as a URL
parameter. The plugins perform no further validation of the session
parameters, other than the cryptographic signature being valid. This is
fixed with the releases issued today by strictly validating that no
session parameters outside of the scope of the respective plugin may be
set.

An unrelated feature in the core system is used to generate redirect links that
