The cache action in action/cache.py allows directory traversal through a crafted HTTP request. An attacker who can upload attachments to the wiki can use this to achieve remote code execution.
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 disabling the cache or the AttachFile action might be possible.
Also, it is of course helpful if you give write permissions (which include uploading attachments) only to trusted users.
This vulnerability was discovered by Michael Chapman.
