The cache action in action/cache.py in MoinMoin through 1.9.10 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.

 https://cve.radiocsirt.org/vuln/ghsa-52q8-877j-gghq GHSA-52q8-877j-gghq — MoinMoin vulnerable to remote code execution via cache action 2026-10-03T22:41:06.288414+00:00

Affected: PyPI: moin

### Impact 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.

### Patches 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.

### Workarounds 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.
