CVE-2026-34079

EUVD-2026-19971
Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory. This allows Flatpak apps  to delete arbitrary files on the host. This vulnerability is fixed in 1.16.4.
