CVE-2026-22567Network attack vector

Administrator-triggered backend function initiation via unvalidated inputs

Published Feb 23, 2026 · Updated Feb 23, 2026

Improper input validation in Zscaler ZIA Admin Portal 6.2 before 6.2r allows remote authenticated users to initiate backend functions. Specific Admin UI fields accept user-supplied values without adequate validation and pass them to unspecified backend functions; Zscaler has not disclosed the fields, validation defect, or invoked operations. Administrative privileges and limited scenarios are required, and the published record bounds the consequence to backend initiation without identifying a specific resulting action.
