The check_ssrf_url guard validates URLs once but requests.get follows redirects and re-resolves DNS without re-validation, enabling attackers to use HTTP redirects or DNS rebinding to access internal addresses and cloud metadata endpoints.","published":"2026-09-04T15:17:45.440","modified":"2026-09-04T15:17:45.440","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/hiyouga/LlamaFactory"},{"type":"WEB","url":"https://github.com/hiyouga/LlamaFactory/blob/v0.9.5/src/llamafactory/api/chat.py"},{"type":"WEB","url":"https://github.com/hiyouga/LlamaFactory/blob/v0.9.5/src/llamafactory/api/common.py"},{"type":"WEB","url":"https://github.com/hiyouga/LlamaFactory/issues/10646"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/llama-factory-ssrf-guard-bypass-via-redirect-and-dns-rebinding"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T15:17:45.440"}}
