Name of the Vulnerable Software and Affected Versions GNUBOARD5 version 5.3.1.9

Description The issue allows remote attackers to inject arbitrary web script or HTML via the bo content head parameter, also known as the "board head contents" parameter, in the adm/board form update.php endpoint. This enables attackers to execute malicious scripts on the victim's browser.
