What is CVE-2026-65013?

The Onlook product version 0.2.32 has a broken object level authorization vulnerability, allowing authenticated attackers to exploit tRPC API endpoints. By supplying arbitrary UUID values to procedures such as project.get, member.remove, and chat.conversation.delete, attackers can gain unauthorized access to other users' resources. This serious flaw enables malicious actors to read, modify, and delete sensitive project data, member lists, and conversation histories without appropriate authorization controls. A patch has been released to remediate this issue.
