While the CLI was waiting for authentication, a malicious web page could send a request to the local callback server with an attacker-controlled token. If accepted before the legitimate callback, the CLI could complete login with the wrong credentials.\n\nThis affects users authenticating the `turbo` CLI against self-hosted remote cache/auth endpoints. Vercel-hosted login flows using device authorization are not affected.\n\n### Fix\n\nThe login and SSO redirect flows now generate a random state value, include it in the browser authentication URL, and require the same value on the localhost callback before accepting a token. Callbacks with a missing or mismatched state are rejected.\n\n### Workarounds\n\nIf you cannot upgrade immediately, avoid browser-based self-hosted `turbo login` or SSO flows on machines that may load untrusted web content during authentication. Use a pre-provisioned token or environment-based authentication instead.","public_affected_ranges":["<= 2.9.13"]}],"null_published_at":"2026-11-05T19:10:21.467Z","source_updated_at":"2026-06-29T15:30:57.000Z","source_disclosed_at":"2026-05-19T19:49:52.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-05T19:05:04.022Z"}],"next_cursor":null,"snapshot_revision":"42594"}
