Comment 1 Thomas Leroy 2022-03-28 09:00:58 UTC

No version containing the fixing commit yet. openSUSE:Factory should be
affected

Comment 2 Ferdinand Thiessen 2022-04-26 19:26:00 UTC

Version on Factory not affected, POC does not work.
Probably only the git version is affected not the 3.0 release (or fixed by other patch).
