Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-21682 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-21682/ (Markdown: https://insights.sbomify.com/CVE-2022-21682/index.md)","id":"CVE-2022-21682","markdown":"https://insights.sbomify.com/CVE-2022-21682/index.md","name":"CVE-2022-21682","record":{"aliases":["ALSA-2022:7458","CLEANSTART-2024-GX04243","DEBIAN-CVE-2022-21682","GHSA-8ch7-5j3h-g4fx","OESA-2022-1788","RHSA-2022:7458","RLSA-2022:7458","UBUNTU-CVE-2022-21682","openSUSE-SU-2024:11755-1","openSUSE-SU-2024:11756-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Flatpak sandboxing framework","requires_auth":"low_privilege","summary":"A malicious application can exploit path traversal in flatpak-builder to execute arbitrary code or modify files outside the build directory.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"flatpak","vendor":"flatpak"},{"product":"flatpak-builder","vendor":"flatpak"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"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 is specified in the manifest, so running `flatpak build` against it will gain those permissions. Normally this will not be done, so this is not problem. However, if `--mirror-screenshots-url` is specified, then flatpak-builder will launch `flatpak build --nofilesystem=host appstream-utils mirror-screenshots` after finalization, which can lead to issues even with the `--nofilesystem=host` protection. In normal use, the only issue is that these empty directories can be created wherever the user has write permissions. However, a malicious application could replace the `appstream-util` binary and potentially do something more hostile. This has been resolved in Flatpak 1.12.3 and 1.10.6 by changing the behaviour of `--nofilesystem=home` and `--nofilesystem=host`.","ecosystems":["AlmaLinux:8","Red Hat:enterprise_linux:8::appstream","Rocky Linux:8","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"flatpak-builder can access files outside the build directory.","id":"CVE-2022-21682","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora","redhat:enterprise_linux"],"type":"path_traversal","year":"2022"},"n_packages":7,"n_references":7,"next":{"headline":"Comment reply notifications sent to incorrect users in wagtail","id":"CVE-2022-21683"},"packages":[{"ecosystem":"AlmaLinux:8","fixed":["1.0.14-2.el8"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder","purl":"pkg:rpm/almalinux/flatpak-builder","source":"ALSA-2022:7458"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:1.0.14-2.el8"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder","purl":"pkg:rpm/redhat/flatpak-builder","source":"RHSA-2022:7458"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:1.0.14-2.el8"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder-debuginfo","purl":"pkg:rpm/redhat/flatpak-builder-debuginfo","source":"RHSA-2022:7458"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:1.0.14-2.el8"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder-debugsource","purl":"pkg:rpm/redhat/flatpak-builder-debugsource","source":"RHSA-2022:7458"},{"ecosystem":"Rocky Linux:8","fixed":["0:1.0.14-2.el8"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder","purl":"pkg:rpm/rocky-linux/flatpak-builder?distro=rocky-linux-8\u0026epoch=0","source":"RLSA-2022:7458"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.12.4-1.1"],"introduced":["0"],"last_affected":[],"package":"flatpak","purl":"pkg:rpm/opensuse/flatpak\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11756-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.2.2-1.1"],"introduced":["0"],"last_affected":[],"package":"flatpak-builder","purl":"pkg:rpm/opensuse/flatpak-builder\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11755-1"}],"prev":{"headline":"Exponential catastrophic backtracking (ReDoS) in marked","id":"CVE-2022-21681"},"products":["flatpak"],"published":"2022-01-13","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"MIT","name":"AlmaLinux","prefix":"ALSA"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"BSD","name":"Rocky Linux","prefix":"RLSA"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["flatpak"]},"summary":"A malicious application can exploit path traversal in flatpak-builder to execute arbitrary code or modify files outside the build directory.","url":"https://insights.sbomify.com/CVE-2022-21682/"}
