CVE-2024-8113Network attack vector

Stored XSS via unescaped placeholder samples

Published Aug 23, 2024 · Updated Aug 30, 2024

Stored XSS in pretix 2024.7.0 and earlier allows remote authenticated users to render arbitrary HTML in another organizer's mail preview. Mail preview code inserts render_sample() output into HTML span content without escaping it, turning organizer-controlled placeholder samples into markup. An event organizer must create the content and another organizer must open a preview for the same event; the default CSP blocks scripts unless separately bypassed.
