"MITRE Corporation reports :

In GLPI before version 9.5.2, the pluginimage.send.php endpoint allows
a user to specify an image from a plugin. The parameters can be
maliciously crafted to instead delete the .htaccess file for the files
directory. Any user becomes able to read all the files and folders
contained in /files/. Some of the sensitive information that is
compromised are the user sessions, logs, and more. An attacker would
be able to get the Administrators session token and use that to
authenticate. The issue is patched in version 9.5.2.");
