CVE-2026-24991Network attack vector

Form submission disclosure via unchecked object key

Published Feb 3, 2026 · Updated Feb 3, 2026

IDOR in Extensions For CF7 3.4.0 and earlier allows remote authenticated users to read stored form submissions via a user-controlled key. The form-data viewing path accepts an attacker-selected object key without verifying the caller's capability to access the referenced submission. Contributor-level access is sufficient, and exposure is limited to submission confidentiality with no published integrity or availability impact.
