Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-28101 in the wild and no public exploit code.\n\nAffected product: flatpak. 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-2023-28101/ (Markdown: https://insights.sbomify.com/CVE-2023-28101/index.md)","id":"CVE-2023-28101","markdown":"https://insights.sbomify.com/CVE-2023-28101/index.md","name":"CVE-2023-28101","record":{"aliases":["CLSA-2025-1740740956","DEBIAN-CVE-2023-28101","GHSA-h43h-fwqx-mpp8","UBUNTU-CVE-2023-28101"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Flatpak package manager","requires_auth":"low_privilege","summary":"Attackers can hide elevated permissions in Flatpak apps using ANSI codes, misleading users via CLI and bypassing security checks.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"flatpak","vendor":"flatpak"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"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 `flatpak(1)` command-line interface by setting other permissions to crafted values that contain non-printable control characters such as `ESC`. A fix is available in versions 1.10.8, 1.12.8, 1.14.4, and 1.15.4. As a workaround, use a GUI like GNOME Software rather than the command-line interface, or only install apps whose maintainers you trust.","ecosystems":[],"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 metadata with ANSI control codes can cause misleading terminal output","id":"CVE-2023-28101","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"Command injection in discordrb","id":"CVE-2023-28102"},"packages":[],"prev":{"headline":"TIOCLINUX can send commands outside sandbox if running on a virtual console","id":"CVE-2023-28100"},"products":["flatpak"],"published":"2023-03-16","related":[{"cvss_score":10,"headline":"TIOCLINUX can send commands outside sandbox if running on a virtual console","id":"CVE-2023-28100","kev_date_added":null,"published":"2023-03-16"},{"cvss_score":9.3,"headline":"Flatpak has a complete sandbox escape leading to host file access and code execution in the host context","id":"CVE-2026-34078","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9,"headline":"Security feature bypass in n/a","id":"CVE-2019-10063","kev_date_added":null,"published":"2019-03-26"},{"cvss_score":8.8,"headline":"Security feature bypass in n/a","id":"CVE-2018-6560","kev_date_added":null,"published":"2018-02-02"},{"cvss_score":8.7,"headline":"Flatpak affected by arbitrary file deletion on the host filesystem","id":"CVE-2026-34079","kev_date_added":null,"published":"2026-04-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-25","vendors":["flatpak"]},"summary":"Attackers can hide elevated permissions in Flatpak apps using ANSI codes, misleading users via CLI and bypassing security checks.","url":"https://insights.sbomify.com/CVE-2023-28101/"}
