Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The file preview functionality in Jirafeau < 4.4.0, which is enabled by default, could be exploited for cross site scripting. An attacker could upload image/svg+xml files containing JavaScript. When someone visits the File Preview URL for this file, the JavaScript inside of this image/svg+xml file will be executed in the users' browser.
