Cap-go before 12.128.12 contains a broken cursor pagination vulnerability in the /private/devices endpoint on the Cloudflare/workerd path that allows authenticated attackers to cause duplicate-page loops and make later rows unreachable. Attackers with app.read_devices access can exploit non-advancing cursor filters to trigger infinite pagination loops, prevent dataset traversal, and cause repeated processing in device-management workflows.
