CVE-2026-19860: JetFormBuilder validation callbacks can delete arbitrary files

A user able to manage forms configures a custom PHP validation callback. A blocklist omits a file-deletion function, allowing the configured callback to delete arbitrary server files when anyone submits the form. Configuration requires form-management access; only the trigger is unauthenticated. The export does not disclose the omitted function or callback-field name. Authoritative affected range: 3.5.6.2 to < 3.6.5.3. Confirmed remediation: 3.6.5.3.
