QID 983255: Python (pip) Security Update for moin (GHSA-52q8-877j-gghq)

Security update has been released for moin to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

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.

CVSS V3 rated as Critical - 9.8 severity.

CVSS V2 rated as High - 7.5 severity.

Solution

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.Workaround:
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.
