Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47346 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- typo3/cms-form (Packagist): affected all versions; fixed in 10.4.57\n- typo3/cms-form (Packagist): affected all versions; fixed in 10.4.57\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-2026-47346/ (Markdown: https://insights.sbomify.com/CVE-2026-47346/index.md)","id":"CVE-2026-47346","markdown":"https://insights.sbomify.com/CVE-2026-47346/index.md","name":"CVE-2026-47346","record":{"aliases":["GHSA-hwvq-2w67-rvxp"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"low_privilege","summary":"Authenticated backend users can bypass file upload restrictions to execute arbitrary SQL and escalate privileges to administrator.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-178","name":"Improper Handling of Case Sensitivity"}],"description":"Backend users with file write permissions were able to upload form definition files with mixed-case extensions (e.g., .FORM.YAML) to bypass the Form Framework's upload restriction.
