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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-39334 exists.\n\nAffected product: nextcloud security-advisories. 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-2022-39334/ (Markdown: https://insights.sbomify.com/CVE-2022-39334/index.md)","id":"CVE-2022-39334","markdown":"https://insights.sbomify.com/CVE-2022-39334/index.md","name":"CVE-2022-39334","record":{"aliases":["DEBIAN-CVE-2022-39334","GHSA-82xx-98xv-4jxv","UBUNTU-CVE-2022-39334"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud CLI client","requires_auth":"low_privilege","summary":"Nextcloud CLI incorrectly trusts invalid TLS certificates, allowing Man-in-the-Middle attacks to expose sensitive data and credentials.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"desktop","vendor":"nextcloud"}],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Nextcloud also ships a CLI utility called nextcloudcmd which is sometimes used for automated scripting and headless servers.
