It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-9840 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-9840/ (Markdown: https://insights.sbomify.com/CVE-2018-9840/index.md)","id":"CVE-2018-9840","markdown":"https://insights.sbomify.com/CVE-2018-9840/index.md","name":"CVE-2018-9840","record":{"aliases":["GHSA-9v25-mc3c-w5v3"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Signal iOS app","requires_auth":"none","summary":"Physically proximate attackers can bypass the screen lock on the Signal iOS app by rapidly interacting with the interface, exposing private data.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"signal","vendor":"signal"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"The Open Whisper Signal app before 2.23.2 for iOS allows physically proximate attackers to bypass the screen locker feature via certain rapid sequences of actions that include app opening, clicking on cancel, and using the home button.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in n/a","id":"CVE-2018-9840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-9841"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2018-9839"},"products":["n/a"],"published":"2018-04-10","related":[{"cvss_score":8.6,"headline":"Denial of service in n/a","id":"CVE-2018-16132","kev_date_added":null,"published":"2018-08-29"},{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2022-28345","kev_date_added":null,"published":"2022-04-15"},{"cvss_score":1,"headline":"Signal App Biometric Authentication missing critical step in authentication","id":"CVE-2025-5715","kev_date_added":null,"published":"2025-06-06"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Physically proximate attackers can bypass the screen lock on the Signal iOS app by rapidly interacting with the interface, exposing private data.","url":"https://insights.sbomify.com/CVE-2018-9840/"}
