{"id":"CVE-2026-63764","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-63764","summary":"LMDeploy Server-Side Request Forgery via HTTP Redirect Bypass","details":"LMDeploy through 0.14.0, fixed in commit 03c3130, contains a server-side request forgery (SSRF) vulnerability in the _load_http_url function within the connection.py media handler, where the private-IP guard validates only the original URL without re-validating hosts after HTTP redirects. An unauthenticated attacker can submit a crafted image_url to the chat completions endpoint pointing to an attacker-controlled host that returns a redirect to a private IP or cloud-metadata endpoint, causing the server to follow the redirect and expose internal service content through the model pipeline.","published":"2026-07-21T20:36:58.372Z","modified":"2026-08-12T03:51:18.660233861Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":{"url":"https://github.com/InternLM/lmdeploy/commit/03c313006d17cc3feae86b633c44206a997c44db","label":"InternLM/lmdeploy@03c3130"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63764.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63764"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/lmdeploy-server-side-request-forgery-via-http-redirect-bypass"},{"type":"REPORT","url":"https://github.com/InternLM/lmdeploy/pull/4734"},{"type":"FIX","url":"https://github.com/InternLM/lmdeploy/commit/03c313006d17cc3feae86b633c44206a997c44db"},{"type":"PACKAGE","url":"https://github.com/InternLM/lmdeploy"},{"type":"EVIDENCE","url":"https://github.com/InternLM/lmdeploy/issues/4761"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.660233861Z"}}
