CVE-2021-21313
In GLPI before verison 9.5.4, there is a vulnerability in the /ajax/common.tabs.php endpoint, indeed, at least two parameters _target and id are not properly sanitized.
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
