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-2025-47287 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tornado (PyPI): affected all versions; fixed in 6.5\n- tornado (PyPI): affected all versions; fixed in 6.5\n- tornado (PyPI): affected all versions; fixed in 6.5\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-2025-47287/ (Markdown: https://insights.sbomify.com/CVE-2025-47287/index.md)","id":"CVE-2025-47287","markdown":"https://insights.sbomify.com/CVE-2025-47287/index.md","name":"CVE-2025-47287","record":{"aliases":["ALSA-2025:8135","ALSA-2025:8136","AZL-61860","AZL-61866","CLEANSTART-2026-XW62361","CLSA-2026-1787299006","DEBIAN-CVE-2025-47287","DLA-4188-1","DSA-5938-1","ECHO-6b4d-4550-0606","GHSA-7cx3-6m66-7c5m","MGASA-2025-0282","OESA-2025-1554","OESA-2025-1555","OESA-2025-1614","OESA-2025-1615","OESA-2025-1905","OESA-2025-2580","PYSEC-2026-1974","RHSA-2025:8135","RHSA-2025:8136","RHSA-2025:8223","RHSA-2025:8226","RHSA-2025:8664","RLSA-2025:8135","RLSA-2025:8136","ROOT-APP-PYPI-CVE-2025-47287","SUSE-SU-2025:01649-1","SUSE-SU-2025:01649-2","SUSE-SU-2025:01726-1","SUSE-SU-2025:01726-2","SUSE-SU-2025:01732-1","SUSE-SU-2025:20430-1","UBUNTU-CVE-2025-47287","USN-7547-1","openSUSE-SU-2025:15153-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python web framework","requires_auth":"none","summary":"Remote attackers can cause denial of service in Tornado by sending malformed multipart form data that triggers excessive synchronous logging.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"tornado","vendor":"tornadoweb"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Tornado is a Python web framework and asynchronous networking library. When Tornado's ``multipart/form-data`` parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous. All versions of Tornado prior to 6.5.0 are affected. The vulnerable parser is enabled by default. Upgrade to Tornado version 6.50 to receive a patch. As a workaround, risk can be mitigated by blocking `Content-Type: multipart/form-data` in a proxy.","ecosystems":["AlmaLinux:10","AlmaLinux:9","PyPI","Red Hat:enterprise_linux:10.0","Red
