    CVE-2026-34078 (GCVE-0-2026-34078)

    Vulnerability from cvelistv5 – Published: 2026-04-07 21:27 – Updated: 2026-07-15 01:04

    Title
    Flatpak has a complete sandbox escape leading to host file access and code execution in the host context
    Summary
    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 to all host files and can be used as a primitive to gain code execution in the host context. This vulnerability is fixed in 1.16.4.
