Comment 1 Jerry James 2026-05-08 01:44:24 UTC 
CVE-2026-41680 affects versions 18.0.0 and 18.0.1 of marked.  The python-jupytext package is currently built with version 16.4.2, before the bug was introduced.  Later versions are not backwards compatible with 16.4.2, so I have left it alone for now.

Also note that marked is used during the build only.  It is not included in the binary python3-jupytext package, so there is no runtime vulnerability anyway.
