{"id":"CVE-2024-32462","state":"PUBLISHED","title":"Flatpak vulnerable to a sandbox escape via RequestBackground portal due to bad argument parsing","description":"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. Normally, the `--command` argument of `flatpak run` expects to be given a command to run in the specified Flatpak app, optionally along with some arguments. However it is possible to instead pass `bwrap` arguments to `--command=`, such as `--bind`. It's possible to pass an arbitrary `commandline` to the portal interface `org.freedesktop.portal.Background.RequestBackground` from within a Flatpak app. When this is converted into a `--command` and arguments, it achieves the same effect of passing arguments directly to `bwrap`, and thus can be used for a sandbox escape. The solution is to pass the `--` argument to `bwrap`, which makes it stop processing options. This has been supported since bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9, 1.12.9, and 1.14.6.","publishedAt":"2024-04-18T18:11:27.680Z","updatedAt":"2025-12-16T18:13:22.363Z","severity":{"score":8.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["flatpak flatpak"],"affected":[{"vendor":"flatpak","product":"flatpak","versions":[{"version":"< 1.10.9","status":"affected"},{"version":">= 1.12.0, < 1.12.9","status":"affected"},{"version":">= 1.14.0, < 1.14.6","status":"affected"},{"version":">= 1.15.0, < 1.15.8","status":"affected"}]}],"references":["https://github.com/flatpak/flatpak/security/advisories/GHSA-phv6-cpc2-2fgj","https://github.com/flatpak/flatpak/commit/72016e3fce8fcbeab707daf4f1a02b931fcc004d","https://github.com/flatpak/flatpak/commit/81abe2a37d363f5099c3d0bdcd0caad6efc5bf97","https://github.com/flatpak/flatpak/commit/b7c1a558e58aaeb1d007d29529bbb270dc4ff11e","https://github.com/flatpak/flatpak/commit/bbab7ed1e672356d1a78b422462b210e8e875931","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZFNSCFJVMAQK5AF55JBN7OSJP3CREDBD/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IB6VQAF5S2YOBULDHPUKPOEIKONOP5KO/","http://www.openwall.com/lists/oss-security/2024/04/18/5"],"weaknesses":["CWE-88"],"ingestedAt":"2026-10-29T20:07:21.467Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/32xxx/CVE-2024-32462.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-32462","state":"PUBLISHED","datePublished":"2024-04-18T18:11:27.680Z","dateUpdated":"2025-12-16T18:13:22.363Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-04-12T19:41:51.164Z"},"containers":{"cna":{"title":"Flatpak vulnerable to a sandbox escape via RequestBackground portal due to bad argument parsing","descriptions":[{"lang":"en","value":"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.
