Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47343 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms-core (Packagist): affected all versions; fixed in 10.4.57\n- typo3/cms-core (Packagist): affected all versions; fixed in 10.4.57\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.51\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.51\n- typo3/cms-core (Packagist): affected from 12.0.0; fixed in 12.4.46\n- typo3/cms-core (Packagist): affected from 12.0.0; fixed in 12.4.46\n- typo3/cms-core (Packagist): affected from 13.0.0; fixed in 13.4.31\n- typo3/cms-core (Packagist): affected from 13.0.0; fixed in 13.4.31\n- typo3/cms-core (Packagist): affected from 14.0.0; fixed in 14.3.3\n- typo3/cms-core (Packagist): affected from 14.0.0; fixed in 14.3.3\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-2026-47343/ (Markdown: https://insights.sbomify.com/CVE-2026-47343/index.md)","id":"CVE-2026-47343","markdown":"https://insights.sbomify.com/CVE-2026-47343/index.md","name":"CVE-2026-47343","record":{"aliases":["GHSA-3v8v-4wg6-r7qh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"low_privilege","summary":"Non-privileged backend users can delete, move, or rename root folders of active file mounts due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Non-privileged backend users with file mount access were able to perform write operations (move, delete, rename) on folders representing the root of an active file mount due to missing authorization restrictions.
