Validate recovery scenario and step when redeeming a confirmation code - #1165
Conversation
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.

Tests cover an accepted scenario and step, and two rejected combinations. ChangesConfirmation-code validation
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: 🟡 Moderate · up to 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 ReviewSecurity architecture risk: 🔵 Low · up to 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.

🟡 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
ConfirmationCodeValidationExecutorTestwith data-driven negative cases and update the “valid code” setup to include scenario/step.

- Line 211: Update the scenario-step validation in
ConfirmationCodeValidationExecutor so it accepts only the specified pairings:
ASK_PASSWORD with UPDATE_PASSWORD, either OTP invitation with SET_PASSWORD, and
either tenant-admin or offline invitation with UPDATE_PASSWORD. Reject
cross-pairings such as ASK_PASSWORD with SET_PASSWORD, and add a rejected
cross-pairing to the test data.

Proposed changes in this pull request
ConfirmationCodeValidationExecutorresolves 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#validateConfirmationCodenow validates the recovery scenario and step of the resolved recovery data against the invitation flows this executor serves:ASK_PASSWORDUPDATE_PASSWORDASK_PASSWORD_VIA_EMAIL_OTPSET_PASSWORDASK_PASSWORD_VIA_SMS_OTPSET_PASSWORDTENANT_ADMIN_ASK_PASSWORDUPDATE_PASSWORDADMIN_INVITE_SET_PASSWORD_OFFLINEUPDATE_PASSWORDAnything 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.updateUserPasswordalready 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.recoveryand 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-fullbranch, and the diff here is intentionally kept identical to it so the two branches do not drift.Follow up actions
