{"id":"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.","modified":"2026-08-12T03:51:18.660233861Z","published":"2026-07-21T20:36:58.372Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63764.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/internlm/lmdeploy","events":[{"introduced":"0"},{"fixed":"03c313006d17cc3feae86b633c44206a997c44db"}],"database_specific":{"cpe":"cpe:2.3:a:internlm:lmdeploy:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"0.14.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v0.14.0","0.14.0a2","v0.13.0","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.11.1","v0.11.0","v0.10.2","v0.10.1","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.0","v0.7.2.post1","v0.7.2","v0.7.1","v0.7.0.post3","v0.7.0.post2","v0.7.0.post1","v0.7.0","0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.6.0a0","v0.5.3","v0.5.2.post1","v0.5.2","v0.5.1","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.0","v0.1.0a2","v0.1.0a1","v0.1.0a0","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63764.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
