Each response applies only to its stated service scope. “Not listed” does not mean unpatched or unaffected.

Response status by service

MOVEit file-transfer workflows for certain customers

Response status: Not listed
Response information checked: 2026-10-29

Current re-audit: Related incident verified; PHP connection not stated · Research date: 2026-10-29

A MOVEit vulnerability in May–June 2023 affected a small number of bespoke customer workflows. The server was disconnected and investigated; Zellis-developed software was unaffected, so this is not a claim of a service-wide payroll leak.

Scope: A PHP connection and response to the current PHP vulnerabilities are not listed.

What users should do

Affected customers were offered a dedicated helpdesk and identity-protection support. Consult the employer’s individual notice and available support.
