Cross-site scripting (XSS) vulnerability in glFusion before 1.1.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

glFusion before 1.1.3 performs authentication with a user-provided password hash instead of a password, which allows remote attackers to gain privileges by obtaining the hash and using it in the glf_password cookie, aka "User Masquerading."

SQL injection vulnerability in private/system/lib-session.php in glFusion 1.1.2 and earlier allows remote attackers to execute arbitrary SQL commands via the glf_session cookie parameter.
