An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-10907 exists.\n\nAffected packages and fixed versions:\n- fschat (PyPI): affected all versions up to 0.2.36; no fix listed\n- fschat (PyPI): affected all versions up to 0.2.36; no fix listed\n- fschat (PyPI): affected all versions up to 0.2.36; no fix listed\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-2024-10907/ (Markdown: https://insights.sbomify.com/CVE-2024-10907/index.md)","id":"CVE-2024-10907","markdown":"https://insights.sbomify.com/CVE-2024-10907/index.md","name":"CVE-2024-10907","record":{"aliases":["GHSA-qg86-f892-m4hj","PYSEC-2026-1398"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FastChat server","requires_auth":"none","summary":"Unauthenticated attackers can cause a denial of service in FastChat by sending malformed multipart requests that trigger an infinite loop.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"fastchat","vendor":"lm-sys"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"In lm-sys/fastchat Release v0.2.36, the server fails to handle excessive characters appended to the end of multipart boundaries.
