Pretalx
Monthly
Unauthenticated attackers can inject malicious HTML into user-controlled template placeholders in pretalx prior to 2026.1.0, enabling arbitrary HTML-rendered emails to be sent from the conference organizer's legitimate sender address. By registering an account with a crafted display name containing HTML or markdown link syntax and triggering a password reset, an attacker can deliver convincing phishing emails that pass SPF/DKIM/DMARC validation, with user interaction (victim clicking password-reset link) required. This vulnerability is fixed in version 2026.1.0.

This vulnerability is fixed in 2026.1.0.
