| CVE-2026-96282 | Low | 0.20 | 3.1 | — | Sep 27, 2026 | A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause… | ||
| CVE-2026-96807 | Med | 0.19 | 4.0 | 0.00 | Sep 23, 2026 | In Flatpak before 1.18.1, a malicious sandboxed app can replace ~/.var/app/$appid/.ld.so with a symlink, causing regenerate_ld_cache to write files at an arbitrary location. The filenames and content are not attacker controlled, making this hard to exploit. | ||
| CVE-2026-97026 | Low | 0.18 | 3.9 | — | Sep 28, 2026 | Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially… | ||
| CVE-2026-97027 | Low | 0.16 | 3.6 | — | Sep 28, 2026 | Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced… | ||
| CVE-2026-96284 | Low | 0.16 | 2.5 | — | Sep 27, 2026 | A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. | ||
| CVE-2026-97025 | Low | 0.14 | 3.2 | — | Sep 28, 2026 | Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only… | ||
| CVE-2024-42472 | Cri | 0.00 | 10.0 | 0.01 | Aug 15, 2024 | Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.14.0 and 1.15.10, a malicious or compromised Flatpak app using persistent directories could access and write files outside of what it would otherwise have access to, which is an attack on… | ||
| CVE-2024-32462 | Hig | 0.00 | 8.4 | 0.01 | Apr 18, 2024 | Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. in versions before 1.10.9, 1.12.9, 1.14.6, and 1.15.8, a malicious or compromised Flatpak app could execute arbitrary code outside its sandbox.

| CVE-2023-28101 | Med | 0.00 | 5.0 | 0.01 | Mar 16, 2023 | Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4, if an attacker publishes a Flatpak app with elevated permissions, they can hide those permissions from users of the… | ||
| CVE-2023-28100 | Cri | 0.00 | 10.0 | 0.01 | Mar 16, 2023 | Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. Versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4 contain a vulnerability similar to CVE-2017-5226, but using the `TIOCLINUX` ioctl command instead of `TIOCSTI`. If a Flatpak… | ||
| CVE-2022-21682 | Hig | 0.00 | 7.7 | 0.02 | Jan 13, 2022 | Flatpak is a Linux application sandboxing and distribution framework. A path traversal vulnerability affects versions of Flatpak prior to 1.12.3 and 1.10.6. flatpak-builder applies `finish-args` last in the build. At this point the build directory will have the full access that… |
