This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

I asked upstream for input in https://github.com/leethomason/tinyxml2/issues/996#issuecomment-3192009888. I’ll work on shipping the probable fix https://github.com/leethomason/tinyxml2/commit/494735de30c946bc7d684c65ff8ece05beeb232d in EPEL10 and Fedora 42+. I do not yet know if it will be practical to backport the probable fix to tinyxml2 9.0.0 in F41 and EPEL9.
Comment 4 Ben Beasley 2025-08-15 17:17:32 UTC 
It looks like 10.1.0 accidentally changed ABI without bumping the SONAME version[1], so the way forward will be to go straight to 11.0.0 (bug 2350891) in F43+. That at least fixes CVE-2024-50615; hopefully it fixes CVE-2024-50614 as well.

I don’t think I will be able to invest the time to try to backport the fix to 10.0.0 or to 9.0.0 without breaking ABI, so F42, F41, EPEL10, and EPEL9 will have to remain as they are. PR’s are welcome, if someone turns out to be more invested in this than I am.
