It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-3820 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2019-3820/ (Markdown: https://insights.sbomify.com/CVE-2019-3820/index.md)","id":"CVE-2019-3820","markdown":"https://insights.sbomify.com/CVE-2019-3820/index.md","name":"CVE-2019-3820","record":{"aliases":["CLEANSTART-2024-BU71046","DEBIAN-CVE-2019-3820","GHSA-jh4v-7q79-jf56","OESA-2021-1403","RHSA-2020:1021","SUSE-SU-2019:1390-1","SUSE-SU-2019:1459-1","UBUNTU-CVE-2019-3820","USN-3966-1","openSUSE-SU-2019:1582-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNOME Shell","requires_auth":"none","summary":"An attacker with physical access to a locked GNOME workstation can bypass lock screen restrictions to invoke keyboard shortcuts and other actions.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"gnome-shell","vendor":"gnome"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions.
