Details

It was discovered that MoinMoin did not properly sanitize certain input,
resulting in a cross-site scripting (XSS) vulnerability. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data, within the same
domain. (CVE-2011-1058)

It was discovered that MoinMoin incorrectly handled group names that
contain virtual group names such as "All", "Known" or "Trusted". This could
result in a remote user having incorrect permissions. (CVE-2012-4404)
