Thank you for the report, and welcome to the community!

This vulnerability has been marked as "disputed" - which means, there is insufficient evidence to show that this vulnerability really exists. The upstream project has confirmed this as well.

Attempting to exploit this vulnerability does not lead to the results as reported.

Was this CVE reported by some sort of security/vulnerability scanner? If so, which scanner software was used?

To answer the question on used scanner software: no, I did not use a specific scanner for this. I just happened to look at xz version and I was previously aware of the vulnerability report for it, was not aware that being disputed made it ok. I must be a little too cautious here. Sorry for the noise.

BTW, I did not find a way to add a note else than using the "Request Feedback on Issue" field.
