CVE-2026-34079

CVE-2026-34079 · Flatpak affected by arbitrary file deletion on the host filesystem

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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 Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory.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.
