@RomanNikitenko Can we move the api calls to the existed Is it possible to move the implementation to the existed oAuthAPI ? |

The data flow is real: the callback URL comes from the OAuth state parameter and reaches Response.temporaryRedirect. It is not unvalidated, though. Immediately before the redirect, authorizeCallbackUrl requires the URL to be located under the status.mainUrl of a DevWorkspace in a namespace of the authenticated user, read from the Kubernetes API for this request. A URL that does not belong to the caller's own workspace is rejected with 403; the callback is additionally required to be https and to carry no userinfo, fragment, percent-encoded path or relative segment.
That allowlist is computed per request and per user, so it is not something the query's sanitizer model can recognise — there is no constant to compare against. Restructuring the check into an inline guard was already tried in a8ef3a4 and did not clear the alert, and Copilot Autofix no longer produces a suggestion for it either. Dismissing as a false positive rather than adding code that only serves to reshape the data flow.

Pls use .get() instead of list

as far as I understand - there is no get() overload that fits here: KubernetesNamespaceFactory exposes only get(RuntimeIdentity) and get(Workspace), and at this point we have neither — resolving which workspaces exist is what this code is for...

`authorizeCallbackUrl` was applied to the callback URL parsed out of `state`, while the value handed to `Response.temporaryRedirect` is a different object built from it by `UriBuilder`. The two cannot disagree today, because `isLocatedUnder` compares origin and path only and the builder just appends query parameters, but the guarantee was not local to the redirect and CodeQL reported `java/unvalidated-url-redirection` for the flow. Repeat the check on the exact URI that is redirected to. The workspace URLs are now resolved once and passed in, so the second check costs nothing: resolving them lists the DevWorkspaces in every namespace of the user, and calling the provider twice would double that per callback.

Use evaluateNamespaceName(), the same resolution NamespaceProvisioner uses, and read DevWorkspaces from that single namespace. Signed-off-by: Roman Nikitenko <rnikiten@redhat.com> Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

What does this PR do?
dynamicURL, but the OAuth application flow requires astaticcallback URL registered in advance. Since different workspaces have different URLs, a single static redirect URI cannot point directly to any specific workspace./api/oauth/ide-redirectendpoint on the Che server that acts as a redirect proxy: it receives the OAuth callback from the identity provider and forwards the authorization code to the originating workspace.status.mainUrlof aDevWorkspaceliving in a namespace of that user. Without this, one user could hand another an authorization URL pointing at their own workspace and collect that user's authorization code.OAuthAuthenticationServiceand delegates toOAuthIdeRedirectManager.UserWorkspaceUrlProviderSPI, with a Kubernetes implementation bound in infrastructure-factory. No new RBAC is required: the che service account already readsDevWorkspaceresources.Screenshot/screencast of this PR
