Bumps omniauth from 2.1.4 to 2.2.0.

Changelog

Sourced from omniauth's changelog.

[2.2.0] - 2026-10-22

Added

• Add a full_host option for each strategy, as a string or a proc that takes the Rack env. It takes precedence over OmniAuth.config.full_host. (#835)
• Ship RBS type signatures for OmniAuth in sig/.
• Document the Rack env keys OmniAuth sets, CSRF protection, sending origin as a form field, and how SameSite session cookies affect the callback in the README. (#909, #1075, #1048, #1149)
• Add this changelog.

Changed

• omniauth.params now includes params posted to the request phase's form, not just its query string, so they survive the POST-only request phase introduced in 2.0. The authenticity_token param is never included (see CVE-2017-18076 under 1.3.2). If your request form posts other fields, they now appear in omniauth.params and are stored in the session until the callback. (#975)
• OmniAuth::Builder builds its middleware stack on the first request and reuses it, instead of rebuilding every strategy on every request. Providers added after the first request are ignored. (#1083, #970)
• Strategy#call sends a request that isn't on the strategy's request or callback path straight to the app, instead of duplicating the strategy for it. It still duplicates it in test mode, with an other_phase, with path lambdas, or when the strategy overrides how #call! dispatches. Methods patched directly onto OmniAuth::Strategy, rather than overridden in a subclass, aren't detected, so a patched #call! no longer runs for requests outside the strategy's paths. (#1172)
• Require Ruby 2.5 or later (was 2.2). (#1167)
• Require Rack 2.2.8 or later (was 2.2.3), rack-protection 2.2.0 or later, and hashie 3.5.2 or later (was 3.4.6).
• The gem now contains only lib, sig, the license, the README, the changelog, and the security policy.

Fixed

• Run the before_callback_phase hook for mocked failures in test mode, as for real callbacks. (#1043, #1171)
• Recognize callback paths with a format suffix, such as /auth/:provider/callback.json. (#618, #1170)
• Don't fail callbacks when the app defines a method named uid, info, credentials, or extra on Object. (#898, #1169)
• Don't add a calculated name to the info hash subsets returned by slice, except, select, and reject. (#892, #1168)
• Collapse repeated slashes in the request path, as Rails routing does, so //auth/:provider from a misconfigured proxy reaches the strategy. (#1079)
• Avoid "instance variable not initialized" warnings on Ruby before 3.0.

Security

• Guard against forged hosts in callback URLs. Unless a full_host is set, OmniAuth builds the callback URL it sends to the provider from the request's Host, X-Forwarded-Host, or Forwarded header, which a client can forge. The new OmniAuth.config.allowed_hosts, a list of strings and regexps, makes the request and callback phases fail with invalid_host unless the request's host matches one of them. Until full_host or allowed_hosts is set, the request phase logs a warning. The README's full_host example, which copied the Host header, is fixed. (GHSA-m27g-v28p-f9fx, CVE-2026-63183)
• Run request_validation_phase before writing omniauth.params to the session, so a cross-site POST rejected by the authenticity check can no longer store attacker-controlled params. (#1162)
