Malicious HTML content could be injected into the page pretix shows when redirection to an untrusted page occurs.

LOW 2.1EPSS 0.29%

Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

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.
