Description
A missing input validation vulnerability in the Fileserver upload API allows an authenticated attacker with file upload privileges to execute stored cross-site scripting (XSS). Successful exploitation could enable the attacker to hijack another CloudVision user's web session, potentially granting full access to their account and administrative permissions.
