Summary

### Impact The `cloudstore.file.upload` action in `server/actions/action_cloudstore_file_upload.go` writes user-supplied filenames directly to disk without proper validation.

This allows unauthenticated attackers to perform path traversal and zip slip attacks, leading to arbitrary file write and potential remote code execution.

**CVSS Score:** 10.0 Critical **CVSS Vector:** CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H **CWE:** CWE-22 (Path Traversal)

### Patches

Upgrade to a patched version once released. The vulnerability affects all versions <= v0.11.3 (latest).

### Workarounds

Restrict access to the cloudstore.file.upload action through authentication and authorization controls until a patch is available.
