CVE-2026-39977 flatpak-builder has a path traversal leading to arbitrary file read on host when installing licence files

flatpak-builder is a tool to build flatpaks from source. From 1.4.5 to before 1.4.8, the license-files manifest key takes an array of paths to user defined licence files relative to the source directory of the module. The paths from that array are resolved using gfileresolverelativepath and...

CVE-2026-39977

The CVE concerns flatpak-builder (versions 1.4.5–1.4.7) where the license-files manifest key accepts an array of paths relative to the module source. Paths are validated using two checks, but the final path component and symlink handling can allow path traversal. The copy operation runs on the ho...

CVE-2026-34078

A flaw was found in Flatpak, a Linux application sandboxing and distribution framework. A malicious application could exploit this by using specially crafted symlinks within the sandbox-expose options of the Flatpak portal. This allows the application to access arbitrary host files and potentiall...

CVE-2026-34079

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 Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory.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

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1.16.4 had a flaw in ld.so cache cleanup: it could delete arbitrary files on the host if the app-controlled path to outdated cache wasn't properly verified within the cache directory.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 has a complete sandbox escape leading to host file access and code execution in the host context

Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the Flatpak portal accepts paths in the sandbox-expose options which can be app-controlled symlinks pointing at arbitrary paths. Flatpak run mounts the resolved host path in the sandbox. This gives apps access ...

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...
