HUBzero CMS allows uploaded files to be placed anywhere

CVE-2026-92970 · published 16 days ago
Summary

When users upload project files in HUBzero CMS version 2.2.32 or earlier, they can trick the system into saving those files outside the intended folder. This lets a signed‑in user write files to locations that the web server can run, which could lead to malicious code being executed. Limit file uploads to trusted members and apply the latest security update or patch from the vendor.
