Is this vulnerability remotely exploitable?

Yes, but it requires authenticated access to the import endpoints. An attacker who can log in as an admin or any role permitted to use POST /api/import/importSY or /api/import/importZipMd can exploit it remotely over HTTP.

What level of access does an attacker need to exploit this?

The attacker typically needs administrative or equivalent privileges within SiYuan, or any account that can invoke the affected import APIs. There is no need for direct filesystem or OS-level access; the HTTP API is sufficient if the account has the relevant permissions.

What is the safest general fix pattern?

The most robust fix is to decouple filesystem paths from user-controlled input. Generate server-side filenames and ensure all paths are resolved, normalized, and verified to reside within a dedicated import directory before any write occurs. Combine this with rigorous validation of archive contents and rejection of paths that attempt to escape the allowed directory.
