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-2023-22473 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-2023-22473/ (Markdown: https://insights.sbomify.com/CVE-2023-22473/index.md)","id":"CVE-2023-22473","markdown":"https://insights.sbomify.com/CVE-2023-22473/index.md","name":"CVE-2023-22473","record":{"aliases":["GHSA-wvr4-gc4c-6vmx"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud Talk Android","requires_auth":"none","summary":"An attacker with physical access can bypass the passcode to view Nextcloud files and conversations in the Talk Android app.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"talk","vendor":"nextcloud"}],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Talk-Android enables users to have video \u0026 audio calls through Nextcloud on Android.
