CVE-2026-111709
WhaTicket Community through commit cf04795 contains an insecure direct object reference vulnerability that allows authenticated agents to access other agents' tickets because ShowTicketService performs no ownership or queue checks.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
