Configuration disclosure via recursively evaluated email placeholders
Published Feb 16, 2026 · Updated Feb 16, 2026
Dynamic variable evaluation in pretix allows remote authenticated users to read sensitive configuration data through crafted email placeholders. Email subjects bypass the placeholder-name safeguards, while subjects and plain-text bodies render substituted placeholder text a second time. Backend template access is normally required; unauthenticated ticket buyers can reach the same disclosure only when a subject uses the buyer-controlled invoice_company placeholder.
