Product Description

OAuth (Authorization Code) providers: the Connect button now submits a form, changing the authorization or token URL requires re-entering the client secret, and the provider page shows who connected it and notes that the connection is shared by the team.

Technical Description

Follow-ups left open in the review of #4624:

• oauth_connect is require_POST; the button submits a CSRF-protected form.
• OAuthAuthorizationCodeConfigForm rejects a masked (unchanged) client secret when authorize_url or token_url changed, so the stored secret can't be sent to a new host without being retyped.
• The callback stores connected_by / connected_at in extra_data.

Not done: restricting a provider to allowed hosts.

Merge risk: medium

Alignment: decent 👀

• The code does the three follow-ups from Add OAuth authorization code provider #4624 that the description lists: Connect is POST-only, the secret must be re-entered when a URL changes, and the callback records connected_by/connected_at. Host allow-listing is listed as not done.
• The description says oauth_connect is require_POST. The code doesn't use require_POST: a GET is redirected to the provider edit page (oauth_views.py). This is probably a better result, but the description doesn't match the code.
• The new "connected by" status text and the note that the connection is shared by the team are user-facing changes. The author says in a comment that the shared-connection note is on purpose.

Impact: medium 👀

• Sensitive area: the OAuth authorization flow and the handling of the client secret (oauth_views.py, forms.py). Both changes make things stricter; neither widens access.
• The secret check runs before super().clean() and compares client_secret with the masked initial value. If the masking or initial_raw work differently from what the check expects, users could be blocked from saving providers whose URLs haven't changed, or the check could silently never fire.
• PII: the connecting user's full name or email is stored in AuthProvider.extra_data and shown to anyone who can view the provider. connected_by is never cleared, so a "reconnect required" status can still show an out-of-date name.
• The Connect <button form="oauth-connect-form"> sits inside the main provider form but targets a separate form placed after it (provider_form.html). If the form= attribute is wrong or the form isn't rendered, clicking Connect would submit or save the main provider form instead.

Verification: poor ⚠️

• The UI changed (the link is now a button, plus the "connected by" text and the shared-connection note) but there are no screenshots or recordings, before or after, and no end-to-end proof that clicking Connect starts the OAuth flow.
• Unit tests cover:
  • redirect on GET with no pending session state
  • the secret re-entry matrix: no change, token URL changed, authorize URL changed, secret re-entered, scope changed
  • connected_by recorded after the callback
• Not tested:
  • a user with no full name and no email, where connected_by is empty
  • creating a new provider, where initial_raw is empty
  • a template or render test that checks the Connect button posts to the connect form

Rollback cost: low ✅

• No migrations. The new extra_data keys only add data and are ignored after a revert, and Connect would go back to working with a GET.

Error detection: good ✅

• A rejected secret shows up as a form error on client_secret, and a GET redirects visibly. No errors are swallowed and no fallbacks were added.

Advisory assessment of 7ed2b09, made by a model from the PR text and diff. It does not set the risk:* label and does not gate merging.

[snopoke]

Fixed the two render tests (back to GET) in the latest commit. The "shared by the team" note in the UI is intentional; it addresses the review's design-risk comment.

Walkthrough

The OAuth provider form now requires secret re-entry when either OAuth URL changes. The connect endpoint accepts POST requests, and the provider page submits the connection action through a CSRF-protected form. The callback records the connecting user and connection time in provider metadata. The provider context exposes the recorded user.

Users whose sessions expire may need to return to the provider page manually before connecting. The change is otherwise mergeable with this limitation.
