CVE-2026-13225Network attack vector

Stored XSS via unsanitized order email

Published Jun 25, 2026 · Updated Jun 25, 2026

Stored XSS in pretix before 2026.3.4, 2026.4.0 through 2026.4.3, and 2026.5.0 through 2026.5.1 allows remote attackers to execute script. The individual-ticket confirmation renderer inserts the stored order email as HTML without sanitizing it before rendering the page. Exploitation requires a user to open that confirmation page; its Content Security Policy constrains the injected HTML unless tracking plugins weaken the policy.
