What is CVE-2017-5480?

A directory traversal vulnerability exists in b2evolution, specifically within the inc/files/files.ctrl.php module. This flaw allows remote authenticated users to manipulate files by providing a '..'

This can lead to significant security risks if exploited, as sensitive data could be exposed or compromised.
