CVE-2026-92970

HUBzero CMS through 2.2.32 contains a path traversal vulnerability in project file upload handlers that allows authenticated project members to write arbitrary files outside the project repository. Attackers can supply traversal sequences in upload parameters to write files to attacker-chosen paths with web server privileges, potentially enabling code execution.
