An attacker with write permissions can upload an SVG file that contains malicious javascript. This javascript will be executed in a user's browser when the user is viewing that SVG file on the wiki.
Users are strongly advised to upgrade to a patched version.
MoinMoin Wiki 1.9.11 has the necessary fixes and also contains other important fixes.
It is not advised to work around this, but to upgrade MoinMoin to a patched version.
That said, a work around via a Content Security Policy in the web server might be possible.
Also, it is of course helpful if you give write permissions (which include uploading attachments) only to trusted users.
