Hi,

The following vulnerability was published for pyxdg, as far I
understand though the impact would be limited as one would need to use
pyxdg with untrusted menu files?

CVE-2019-12761[0]:
| A code injection issue was discovered in PyXDG before 0.26 via crafted
| Python code in a Category element of a Menu XML document in a .menu
| file. XDG_CONFIG_DIRS must be set up to trigger xdg.Menu.parse parsing
| within the directory containing this file. This is due to a lack of
| sanitization in xdg/Menu.py before an eval call.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
