pretix Stored Cross-site Scripting vulnerability
Date: 2024-08
Affected: pip/pretix
Attack vector: xss
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2024-8113
CWE: CWE-79

Stored XSS in organizer and event settings of pretix up to 2024.7.0 allows malicious event organizers to inject HTML tags into e-mail previews on settings page. The default Content Security Policy of pretix prevents execution of attacker-provided scripts, making exploitation unlikely. However, combined with a CSP bypass (which is not currently known) the vulnerability could be used to impersonate other organizers or staff users.
