Stored Cross-Site Scripting (XSS) vulnerability discovered in the Properties Component of JATOS v3.9.3. This flaw allows an attacker to inject malicious JavaScript into the properties section of a study, specifically within the UUID field. When an admin user accesses the study's properties, the injected script is executed in the admin's browser, which could lead to unauthorized actions, including account compromise and privilege escalation.
