Description
CVE-2026-19127 is a medium severity vulnerability in GitroomHQ's postiz-app affecting the billing and license activation subsystem. It allows remote attackers to bypass payment authorization by exploiting weak cryptographic validation or missing server-side state checks on promotional or lifetime-deal redemption codes. This enables unauthenticated attackers to forge or replay redemption tokens to activate the highest-tier paid subscriptions without payment.
