What is CVE-2026-94211?

A vulnerability has been identified in Hyve5 Leantime up to version 3.9.8, specifically affecting the Project Dashboard component. This flaw allows malicious actors to inject cross-site scripting (XSS) payloads through the '/app/Domain/Dashboard/Templates/show.blade.php' file. The manipulation of project dashboard content can expose users to security risks, as the raw output of manipulated data is displayed to anyone viewing the project dashboard. An 'EDIT perm' is required to execute the attack, making it a potential vector for privilege escalation. Despite early disclosure attempts to the vendor, no response was received regarding this critical issue.
