An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34421 in the wild and no public exploit code.\n\nAffected product: Zoom Video Communications Inc Keybase Client for Android. 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-2021-34421/ (Markdown: https://insights.sbomify.com/CVE-2021-34421/index.md)","id":"CVE-2021-34421","markdown":"https://insights.sbomify.com/CVE-2021-34421/index.md","name":"CVE-2021-34421","record":{"aliases":["GHSA-9j45-jfq7-hc4v"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Keybase mobile client","requires_auth":"none","summary":"Attackers can recover sensitive data from Keybase mobile apps if exploded messages are not properly deleted when the app is backgrounded.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zoom","cpe":[{"product":"keybase","vendor":"keybase"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"The Keybase Client for Android before version 5.8.0 and the Keybase Client for iOS before version 5.8.0 fails to properly remove exploded messages initiated by a user if the receiving user places the chat session in the background while the sending user explodes the messages.
