FTR: The issue was fixed back in 2019 via the same patch submitted here by Pedro and upstream never consider it a security bug [0], indeed they add it to a "Bogus security vulnerabilities" section in their security advisories page [1].

Now disputed in Mitre [0] and NVD [1]. Hence, I flag it as invalid on our internal vulnerability tracker.
