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-2023-49790 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nextcloud (Bitnami): affected all versions; fixed in 4.9.2\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-2023-49790/ (Markdown: https://insights.sbomify.com/CVE-2023-49790/index.md)","id":"CVE-2023-49790","markdown":"https://insights.sbomify.com/CVE-2023-49790/index.md","name":"CVE-2023-49790","record":{"aliases":["BIT-nextcloud-2023-49790","GHSA-j8g7-88vv-rggv"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud iOS Files app","requires_auth":"none","summary":"Attackers can bypass the PIN code lock in the Nextcloud iOS Files app to access protected data without authentication.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nextcloud","vendor":"nextcloud"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The Nextcloud iOS Files app allows users of iOS to interact with Nextcloud, a self-hosted productivity platform.
