An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-43543 in the wild and no public exploit code.\n\nAffected product: KDDI +Message App for Android and for iOS, NTT DOCOMO +Message App for Android and for iOS, and SoftBank +Message App for Android and for iOS. 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-2022-43543/ (Markdown: https://insights.sbomify.com/CVE-2022-43543/index.md)","id":"CVE-2022-43543","markdown":"https://insights.sbomify.com/CVE-2022-43543/index.md","name":"CVE-2022-43543","record":{"aliases":["GHSA-jxxq-8qw2-56g4"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Carrier messaging app","requires_auth":"none","summary":"Attackers can spoof URLs in messaging apps by exploiting improper Unicode handling, facilitating phishing attacks against users.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"\\+_message","vendor":"docomo"},{"product":"\\+_message","vendor":"kddi"},{"product":"\\+_message","vendor":"softbank"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"KDDI +Message App, NTT DOCOMO +Message App, and SoftBank +Message App contain a vulnerability caused by improper handling of Unicode control characters. +Message App displays text unprocessed, even when control characters are contained, and the text is shown based on Unicode control character's specifications.
