What is CVE-2026-28790?

OliveTin has a vulnerability that exposes system stability to potential attacks via an unauthenticated user access point. This issue, present in versions before 3000.11.0, allows guests to terminate ongoing actions using the KillAction RPC, despite the authentication requirement for guest logins being enabled. While dashboard access is properly restricted for unauthenticated users, they can still exploit this flaw to disrupt legitimate action executions, leading to unauthorized denial of service. The vulnerability has been effectively patched in version 3000.11.0.

Affected Version(s)

OliveTin < 3000.11.0
