The upstream and plugin methods release the entry guard before the final mutation. A concurrent delete can run between the update check and insertion, which resurrects the deleted resource. A concurrent update can also run before deletion, which lets deletion remove a newer value while returning the older value.
Keep the existence check, tenant check, and mutation in one atomic entry operation.

⚠️ Unverified finding
Verification did not complete.Authorize the OAuth2 credential destination.
Plugin configuration supplies
token_endpointorissuer_url. The plugin then sends resolved client credentials throughfetch_token.No local control restricts the destination to an approved identity provider. An authenticated configuration editor can select an attacker-controlled endpoint and cause the gateway to disclose a credential that the editor can reference.
Verify that control-plane validation enforces a tenant-scoped identity-provider allowlist. If it does not, enforce the policy before secret resolution and token acquisition.
