version 1.9.6 :

- remote code execution vulnerability in twikidraw/anywikidraw action,

- path traversal vulnerability in AttachFile action,

- XSS issue, escape page name in rss link.

CVE entries at MITRE furher clarify :

Multiple unrestricted file upload vulnerabilities in the (1) twikidraw
(action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py)
actions in MoinMoin before 1.9.6 allow remote authenticated users with
write permissions to execute arbitrary code by uploading a file with
an executable extension, then accessing it via a direct request to the
file in an unspecified directory, as exploited in the wild in July
2012.

Directory traversal vulnerability in the _do_attachment_move function
in the AttachFile action (action/AttachFile.py) in MoinMoin 1.9.3
through 1.9.5 allows remote attackers to overwrite arbitrary files via
a .. (dot dot) in a file name.

Cross-site scripting (XSS) vulnerability in the rsslink function in
theme/__init__.py in MoinMoin 1.9.5 allows remote attackers to inject
arbitrary web script or HTML via the page name in a rss link."
