CiviForm simplifies applications for government benefits programs by reusing applicant data across multiple benefit applications. Prior to 3.33.0, GET /admin/tiDash/editClientForm/:accountId verifies that the requester is a Trusted Intermediary but showEditClientForm performs a raw lookupAccount(accountId) without confirming that the citizen account belongs to the requester's trustedIntermediaryGroup. An authenticated Trusted Intermediary can enumerate accountId values and read the applicant display name, including the citizen's name and email address, for accounts outside the intermediary's group. This issue is fixed in version 3.33.0.
