CiviForm: Trusted-Intermediary IDOR discloses any citizen's name and email

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
