# Seafile SeaDoc converter: path traversal lets attackers run code

Link for people: https://infrastack.ai/live/CVE-2026-129167 (this .md is for agents)

The Seafile SeaDoc converter accepts an absolute filename in its confluence-to-wiki API, so a ZIP can be extracted into the Python library path. An attacker holding a public share token can then trigger an import of that module and execute code on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Seafile SeaDoc converter affected range not listed fixed no fixed version listed

## How to check

- Check the installed SeaDoc converter version against the affected ranges (2.0.4 before 2.0.11, and 3.0.0 before 3.0.8).

## Fix

- SeaDoc converter 2.0.x: move to `2.0.11` or later.
- SeaDoc converter 3.0.x: move to `3.0.8` or later.

## From the sources

Seafile SeaDoc converter 2.0.4 before 2.0.11 and 3.0.0 before 3.0.8 contains an absolute path traversal vulnerability that allows unauthenticated attackers holding a public share token to execute code. Attackers supply an absolute filename to /api/v1/confluence-to-wiki/ to extract a ZIP from download_url into the Python library path, then trigger the module's import via a file-convert request.
