Proposed changes in this pull request

ConfirmationCodeValidationExecutor resolves a confirmation code to its recovery data and then checks only the tenant domain. Any unexpired code belonging to the same tenant is therefore accepted by this executor, regardless of the recovery scenario and step it was issued for — for example a code issued for notification based password recovery is accepted by the invited user registration flow.

  • ConfirmationCodeValidationExecutor#validateConfirmationCode now validates the recovery scenario and step of the resolved recovery data against the invitation flows this executor serves:

    Scenario Step Issued by
    ASK_PASSWORD UPDATE_PASSWORD invitation via email link
    ASK_PASSWORD_VIA_EMAIL_OTP SET_PASSWORD invitation via email OTP
    ASK_PASSWORD_VIA_SMS_OTP SET_PASSWORD invitation via SMS OTP
    TENANT_ADMIN_ASK_PASSWORD UPDATE_PASSWORD tenant admin invitation
    ADMIN_INVITE_SET_PASSWORD_OFFLINE UPDATE_PASSWORD offline invitation link
  • Anything outside this set is reported as a plain invalid code (ERROR_CODE_INVALID_CODE), so the response does not reveal whether the code exists or which scenario it belongs to. The rejected scenario and step are logged at debug level only.

  • NotificationPasswordRecoveryManager.updateUserPassword already validates the step this way; this restores that check in the flow executor and adds the scenario dimension.

  • ConfirmationCodeValidationExecutorTest — the existing valid-code test now stubs a scenario and step, and a new data-driven rejection test covers a code from an unrelated scenario and a served scenario at a step that does not authorise a password change.

No API, configuration, database or UI change is involved, so there is no migration or documentation impact.

When should this PR be merged

No preconditions. The change is self-contained within org.wso2.carbon.identity.recovery and is a straight behaviour tightening on an existing validation path.

Note on scope: this mirrors an equivalent change already merged on the support-1.15.9.x-full branch, and the diff here is intentionally kept identical to it so the two branches do not drift.

Follow up actions

  • None required.

Checklist (for reviewing)

General

  • Is this PR explained thoroughly? All code changes must be accounted for in the PR description.
  • Is the PR labeled correctly?

Functionality

  • Are all requirements met? Compare implemented functionality with the requirements specification.
  • Does the UI work as expected? There should be no Javascript errors in the console; all resources should load. There should be no unexpected errors. Deliberately try to break the feature to find out if there are corner cases that are not handled.

Code

  • Do you fully understand the introduced changes to the code? If not ask for clarification, it might uncover ways to solve a problem in a more elegant and efficient way.
  • Does the PR introduce any inefficient database requests? Use the debug server to check for duplicate requests.
  • Are all necessary strings marked for translation? All strings that are exposed to users via the UI must be marked for translation.

Tests

  • Are there sufficient test cases? Ensure that all components are tested individually; models, forms, and serializers should be tested in isolation even if a test for a view covers these components.
  • If this is a bug fix, are tests for the issue in place? There must be a test case for the bug to ensure the issue won’t regress. Make sure that the tests break without the new code to fix the issue.
  • If this is a new feature or a significant change to an existing feature? has the manual testing spreadsheet been updated with instructions for manual testing?

Security

  • Confirm this PR doesn't commit any keys, passwords, tokens, usernames, or other secrets.
  • Are all UI and API inputs run through forms or serializers?
  • Are all external inputs validated and sanitized appropriately?
  • Does all branching logic have a default case?
  • Does this solution handle outliers and edge cases gracefully?
  • Are all external communications secured and restricted to SSL?

Documentation

  • Are changes to the UI documented in the platform docs? If this PR introduces new platform site functionality or changes existing ones, the changes should be documented.
  • Are changes to the API documented in the API docs? If this PR introduces new API functionality or changes existing ones, the changes must be documented.
  • Are reusable components documented? If this PR introduces components that are relevant to other developers (for instance a mixin for a view or a generic form) they should be documented in the Wiki.

Testing: ConfirmationCodeValidationExecutorTest — 5 tests, 0 failures. The two new rejection cases fail without the executor change and pass with it.

ConfirmationCodeValidationExecutor resolved a confirmation code to its
recovery data and then checked only the tenant domain, so any unexpired
code of the same tenant was accepted regardless of the recovery scenario
and step it had been issued for.

Validate the scenario and step in validateConfirmationCode against the
pairings this executor serves (ASK_PASSWORD, ASK_PASSWORD_VIA_EMAIL_OTP,
ASK_PASSWORD_VIA_SMS_OTP, TENANT_ADMIN_ASK_PASSWORD and
ADMIN_INVITE_SET_PASSWORD_OFFLINE at UPDATE_PASSWORD or SET_PASSWORD).
Anything else is reported as a plain invalid code.
NotificationPasswordRecoveryManager.updateUserPassword already validates
the step this way; this restores that check in the flow executor and adds
the scenario dimension.

📝 Walkthrough

Walkthrough

Confirmation-code validation now checks the recovery scenario and step, in addition to the tenant domain. Tests cover an accepted scenario and step, and two rejected combinations.

Changes

Confirmation-code validation

Layer / File(s) Summary
Validate recovery scenario and step
components/org.wso2.carbon.identity.recovery/src/main/java/org/wso2/carbon/identity/recovery/executor/ConfirmationCodeValidationExecutor.java, components/org.wso2.carbon.identity.recovery/src/test/java/org/wso2/carbon/identity/recovery/executor/ConfirmationCodeValidationExecutorTest.java
The executor accepts five invitation scenarios and either UPDATE_PASSWORD or SET_PASSWORD. It rejects other scenarios or steps with an invalid-code client exception. Tests cover one accepted context and two rejected contexts.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 08be8

The new check is meant to accept a confirmation code only for its specific scenario and step. It currently allows mismatched combinations, such as an ask-password code at the set-password step, so the validation is looser than intended. Pairing the checks and adding a mismatched test case should be done before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 08be8

The change restricts which confirmation codes can reach invited-user password setup. It does not enforce every scenario-and-step pairing described in the change, however, and interruption behavior after a password update remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — A person with a stored, tenant-matched code accepted by this executor can proceed toward the invited user's credential update. The added check reduces the set of accepted codes but leaves mismatched combinations of its allowed scenarios and steps eligible.

Security Findings and Attack Paths

  • inferred — A stored code bearing an allowed scenario with the wrong allowed step would pass this gate. This incomplete pairing control is not an established PR-introduced attack path: base behavior accepted that code as well, and issuance of such mismatched records was not established.

Trust Boundaries and Controls

  • observed — The tenant check remains ahead of the new validation, and a rejected scenario or step prevents the executor from setting the recovered user and code in flow context.

Resilience and Maintainability Implications

  • inferred — Successful completion provides a code-invalidation path, but the available execution path does not prove atomic consumption with the credential update or establish replay behavior after interruption. These operations were not changed by this PR.

Hardening Proposals

  • proposed — If the intended contract is the five stated pairings, validate each scenario together with its corresponding step and exercise mismatched allowed-set combinations in tests.

🟡 Changes recommended

The executor currently validates scenario and step independently rather than enforcing the specific scenario→step pairings described, which can still allow unintended combinations.

What changed in this PR

This PR tightens confirmation-code redemption in ConfirmationCodeValidationExecutor so that a code is only accepted when it was issued for the correct recovery scenario and step for invited-user password setup flows, preventing cross-flow code reuse within the same tenant.

Changes:

  • Add recovery scenario + step validation when resolving a confirmation code in the executor.
  • Extend ConfirmationCodeValidationExecutorTest with data-driven negative cases and update the “valid code” setup to include scenario/step.
File Description
components/​org.wso2.carbon.identity.recovery/​src/​main/​java/​org/​wso2/​carbon/​identity/​recovery/​executor/​ConfirmationCodeValidationExecutor.java Adds scenario/step validation during confirmation-code redemption.
components/​org.wso2.carbon.identity.recovery/​src/​test/​java/​org/​wso2/​carbon/​identity/​recovery/​executor/​ConfirmationCodeValidationExecutorTest.java Adds scenario/step-aware mocks and negative test cases via a data provider.
