CVE-2026-34079

Flatpak (Linux application sandboxing) before version 1.16.4 had a flaw in ld.so cache cleanup: it could delete arbitrary files on the host if the app-controlled path to outdated cache wasn't properly verified within the cache directory. The vulnerability is fixed in 1.16.4. Impact is described a...

CVE-2026-34078

Flatpak before 1.16.4 is vulnerable: the portal accepts paths in sandbox-expose options that can be app-controlled symlinks to arbitrary host paths, and Flatpak run mounts the resolved host path in the sandbox. This can give apps access to all host files and may be a primitive for host-context co...
