{"id":"CVE-2026-107207","summary":"LMCache through 0.5.5 Missing Authentication in Frontend Node Catalog Allows SSRF Allowlist Bypass","details":"LMCache through 0.5.5 contains a server-side request forgery vulnerability in its frontend monitoring service that allows unauthenticated attackers to bypass the proxy allowlist by registering arbitrary hosts. Attackers can add entries via POST /api/proxies and then use /proxy or /proxy2 to reach internal hosts, read responses, and tamper with nodes or stop the heartbeat.","modified":"2026-10-08T10:31:07.456970541Z","published":"2026-10-07T15:24:05.336Z","database_specific":{"cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107207.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107207.json"},{"type":"PACKAGE","url":"https://github.com/LMCache/LMCache"},{"type":"ARTICLE","url":"https://github.com/LMCache/LMCache/blob/v0.5.5/lmcache/lmcache_frontend/app.py#L411-L428"},{"type":"ARTICLE","url":"https://github.com/LMCache/LMCache/blob/v0.5.5/lmcache/lmcache_frontend/app.py#L567-L604"},{"type":"REPORT","url":"https://github.com/LMCache/LMCache/issues/5512"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107207"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/lmcache-through-0.5.5-missing-authentication-in-frontend-node-catalog-allows-ssrf-allowlist-bypass"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/lmcache/lmcache","events":[{"introduced":"0"},{"last_affected":"05a013b29da78cf2321b9b46ec5039dde2fb0bb0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.5.5"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.5.5rc7-xpu","v0.5.5rc7-rocm-torch210","v0.5.5rc7-rocm","v0.5.5rc7-musa","v0.5.5rc7-cu129","v0.5.5rc7","v0.5.5-xpu","v0.5.5-rocm-torch210","v0.5.5-rocm","v0.5.5-musa","v0.5.5-cu129","v0.5.5","v0.5.5rc6-rocm-torch210","v0.5.5rc6-cu129","v0.5.5rc6","nightly-rocm-2026-09-09-xpu","nightly-rocm-2026-09-09-rocm-torch210","nightly-rocm-2026-09-09-rocm","nightly-rocm-2026-09-09-musa","nightly-rocm-2026-09-09-cu129","nightly-rocm-2026-09-09","nightly-musa","v0.5.5rc5-xpu","v0.5.5rc5-rocm-torch210","v0.5.5rc5-rocm","v0.5.5rc5-musa","v0.5.5rc5-cu129","v0.5.5rc5","v0.5.5rc4-xpu","v0.5.5rc4-rocm-torch210","v0.5.5rc4-rocm","v0.5.5rc4-cu129","v0.5.5rc4","v0.5.5rc3-xpu","v0.5.5rc3-rocm-torch210","v0.5.5rc3-rocm","v0.5.5rc3-cu129","v0.5.5rc3","v0.5.5rc2-xpu","v0.5.5rc2-rocm-torch210","v0.5.5rc2-rocm","v0.5.5rc2-cu129","v0.5.5rc2","nightly-cu129","nightly-rocm","nightly","v0.5.5rc1-xpu","v0.5.5rc1-rocm","v0.5.5rc1-cu129","v0.5.5rc1","operator-v0.5.4","v0.5.4-cu129","v0.5.4rc5-cu129","v0.5.4","v0.5.4rc5","v0.5.4rc4-rocm","v0.5.4rc4-cu129","v0.5.4rc4","v0.5.4rc3-cu129","v0.5.4rc3","v0.5.4rc2-rocm","v0.5.4rc2-cu129","v0.5.4rc2","v0.5.4rc1-rocm","v0.5.4rc1-cu129","operator-v0.5.3","v0.5.4rc1","operator-v0.5.3rc1","v0.5.3-rocm","v0.5.3-cu129","v0.5.3rc4-rocm","v0.5.3rc4-cu129","v0.5.3","v0.5.3rc4","v0.5.3rc3-cu129","v0.5.3rc3-rocm","v0.5.3rc3","v0.5.3.rc3-rocm","v0.5.3.rc3","v0.5.3rc2-rocm","v0.5.3rc2-cu129","v0.5.3rc2","v0.5.3rc1-rocm","v0.5.3rc1-cu129","v0.5.3rc1","operator-v0.5.2","operator-v0.5.1","v0.5.2-cu129","v0.5.2rc1-cu129","v0.5.2rc1","v0.5.2","operator-v0.5.1rc1","v0.5.1-cu129","v0.5.1rc2-cu129","v0.5.1rc2","v0.5.1rc1-cu129","v0.5.1","v0.5.1rc1","operator-v0.5.0rc3","operator-v0.5.0","operator-v0.5.0rc2","operator-v0.5.0rc1","v0.5.0-cu129","v0.5.0rc1-cu129","v0.5.0rc1","v0.5.0","v0.4.8rc4-cu129","operator-v0.4.8rc1","v0.4.8rc4","v0.4.8rc3-cu129","v0.4.8rc3","v0.4.7-cu129","v0.4.7","v0.4.6-cu129","v0.4.6","operator-v0.1.1","operator-latest","v0.4.5-cu129","v0.4.5","nightly-cu13","v0.4.4-cu13","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","operator-nightly-latest","v0.3.15","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10post2","v0.3.10.post1","v0.3.10","v0.3.9post2","v0.3.9post1","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1.post1","v0.3.1","v0.3.0","v0.2.1","v0.2.0","v0.1.4-alpha","v0.1.3-alpha","v0.1.2-alpha","v0.1.1-alpha","v0.1.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107207.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:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
