What is CVE-2019-12761?
CVE-2019-12761 is a high-severity code injection vulnerability in n/a, published on 6 Jun 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-94
