Bumps [oauthlib](https://github.com/oauthlib/oauthlib) from 4.0.0 to 4.0.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/oauthlib/oauthlib/releases";>oauthlib's releases</a>.</em></p> <blockquote> <h2>4.0.1</h2> <h2>Security</h2> <ul> <li><strong>CVE-2026-49272</strong> / GHSA-3jp2-3mrg-2vxc: The device code flow token endpoint did not validate the <code>device_code</code> parameter. A request with a known <code>client_id</code> and a bogus <code>device_code</code> could obtain a bearer token. <code>DeviceCodeGrant.validate_token_request</code> now calls <code>DeviceCodeGrant.validate_device_code()</code>, which rejects missing or unknown device codes (<code>invalid_request</code> / <code>invalid_grant</code>) and delegates the code's authorization status to the new <code>RequestValidator.validate_device_code()</code> hook, per RFC 8628 Section 3.5. (cherry-picked from <a href="https://redirect.github.com/oauthlib/oauthlib/issues/954";>#954</a>)</li> </ul> <h2>Upgrade note for device flow integrators</h2> <p>Custom <code>RequestValidator</code> implementations using the device flow must now implement <code>validate_device_code(client_id, code, request)</code>. Return one of the <code>DeviceCodeGrant.DEVICE_CODE_*</code> statuses for known codes, or <code>None</code> for an unknown code. When returning <code>AUTHORIZED</code>, the validator must also populate <code>request.user</code> and <code>request.scopes</code> from the stored authorization.</p> </blockquote> </details> <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/oauthlib/oauthlib/blob/v4.0.1/CHANGELOG.rst";>oauthlib's changelog</a>.</em></p> <blockquote> <h2>4.0.1 (2026-11-04):</h2> <p>OAuth2.0 Provider (Security):</p> <ul> <li> <p><strong>Security</strong>: CVE-2026-49272 / GHSA-3jp2-3mrg-2vxc: The device code flow token endpoint did not validate the <code>device_code</code> parameter.
