CVE-2026-75030Network attack vector

Unauthorized mass group membership changes via task execution

Published Sep 14, 2026 · Updated Sep 14, 2026

Missing authorization in Apache Syncope allows remote authenticated users to mass provision or deprovision group members through task execution. The task execution path checks task entitlements but does not enforce group-related administration capabilities before applying membership changes across a group. Affected releases are 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.7, and 4.1.0-M0 through 4.1.2; administrator task-execution entitlements are required.
