What is CVE-2019-9093?

A security flaw has been identified in Humhub Community Edition 1.3.10, which exposes the application to a reflected Cross Site Scripting (XSS) attack. The vulnerability stems from the 'file/file/upload' functionality, where user-supplied input in the filename parameter is not properly validated. This lack of input sanitization allows attackers to inject malicious JavaScript payloads that are echoed back to users, potentially compromising their session or redirecting them to harmful sites. Webmasters using this version should prioritize updating their systems to mitigate this risk.
