Apache Syncope admins could change many group members

CVE-2026-75030 · published 11 days ago
Summary

In Apache Syncope versions up to 3.0.16, 4.0.7, and 4.1.2, an administrator who is only allowed to run tasks can add or remove large numbers of users from groups even without proper group‑management rights. This could unintentionally give people access they shouldn’t have or take away access from those who need it. The issue is fixed in Apache Syncope 4.0.8 and 4.1.3, so upgrade to one of those versions promptly.
