An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15305 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms-form (Packagist): affected from 14.2.0; fixed in 14.3.5\n- typo3/cms-form (Packagist): affected from 14.2.0; fixed in 14.3.5\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-2026-15305/ (Markdown: https://insights.sbomify.com/CVE-2026-15305/index.md)","id":"CVE-2026-15305","markdown":"https://insights.sbomify.com/CVE-2026-15305/index.md","name":"CVE-2026-15305","record":{"aliases":["GHSA-mfqj-cqv3-h7xw"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"TYPO3 CMS","requires_auth":"none","summary":"Attackers can upload malicious files to TYPO3 forms if MIME type restrictions are configured, potentially leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-351","name":"Insufficient Type Distinction"}],"description":"Users were able to upload files with arbitrary MIME types to forms using FileUpload or ImageUpload elements with allowedMimeTypes configured.
