A vulnerability was found in YACS (the affected version unknown). It has been classified as critical. Affected is an unknown part of the file users/user.php. The manipulation of the argument context[path_to_root] with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
