The user form processing (userform.py) in MoinMoin before 1.6.3, when using ACLs or a non-empty superusers list, does not properly manage users, which allows remote attackers to gain privileges.
Multiple cross-site scripting (XSS) vulnerabilities in action/AttachFile.py in MoinMoin 1.8.2 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) an AttachFile sub-action in the errormsg function or (2) multiple vectors related to package file errors in the uploadform function, different vectors than CVE-2009-0260.
Cross-site scripting (XSS) vulnerability in MoinMoin 1.5.x through 1.5.8 and 1.6.x before 1.6.1 allows remote attackers to inject arbitrary web script or HTML via the login action.
