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-2026-45153 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nextcloud (Bitnami): affected from 33.0.0; fixed in 33.1.0\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-2026-45153/ (Markdown: https://insights.sbomify.com/CVE-2026-45153/index.md)","id":"CVE-2026-45153","markdown":"https://insights.sbomify.com/CVE-2026-45153/index.md","name":"CVE-2026-45153","record":{"aliases":["BIT-nextcloud-2026-45153","GHSA-2w7v-5299-3hw5"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud Files app","requires_auth":"low_privilege","summary":"Attackers can bypass the Nextcloud Files app PIN on Android by pressing the back button after unlocking the device.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Nextcloud is an open source content collaboration platform.
