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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N","score":4.5},"cwes":["CWE-639"],"references":["https://github.com/civiform/civiform/commit/ccfd84ff2d9ee6570a1b1524c7ae3a3732e1839e","https://github.com/civiform/civiform/pull/13635","https://github.com/civiform/civiform/releases/tag/v3.33.0","https://github.com/civiform/civiform/security/advisories/GHSA-qv7c-9hjr-9rv7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107856","score":0.00233,"percentile":0.14104,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
