{"id":"CVE-2026-49445","summary":"Cilium: Sensitive information disclosure and cluster disruption via local Envoy admin socket access","details":"Cilium is a networking, observability, and security solution. Prior to 1.17.14, 1.18.8, and 1.19.2, when Cilium L7 functionality is enabled, the embedded or standalone Envoy instance creates a world-accessible admin.sock on cluster nodes, allowing a local attacker to access Envoy admin endpoints, expose TLS secrets, disrupt cluster traffic, or terminate Envoy. This issue is fixed in versions 1.17.14, 1.18.8, and 1.19.2.","aliases":["BIT-cilium-2026-49445","BIT-cilium-operator-2026-49445","BIT-hubble-relay-2026-49445","GHSA-3fcv-jvfp-m4q9","GO-2026-5905"],"modified":"2026-08-05T03:47:35.841636266Z","published":"2026-07-15T19:11:55.303Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"fixed":"1.17.14"},{"introduced":"1.18.0"},{"fixed":"1.18.8"},{"introduced":"1.19.0"},{"fixed":"1.19.2"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-732"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49445.json"},"references":[{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.17.14"},{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.18.8"},{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.19.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49445.json"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-3fcv-jvfp-m4q9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49445"},{"type":"FIX","url":"https://github.com/cilium/cilium/commit/7bfbdd5c1be83d6c9ba3e089b4c804b6603505b6"},{"type":"FIX","url":"https://github.com/cilium/cilium/pull/44512"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cilium/cilium","events":[{"introduced":"0"},{"fixed":"7bfbdd5c1be83d6c9ba3e089b4c804b6603505b6"},{"fixed":"6fc7f9725d4a2f3293b17614181ae2b3fb5529cf"},{"fixed":"7d6f03efca0e1df5fcc8face71e35b40ab7a75a0"},{"fixed":"3977f6a1120bf5ec0206c1b3c484ba094da82c7d"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v1.19.1","1.19.1","v1.17.13","1.17.13","v1.18.7","1.18.7","v1.19.0","1.19.0","v1.19.0-rc.1","1.19.0-rc.1","v1.19.0-rc.0","1.19.0-rc.0","v1.18.6","1.18.6","v1.17.12","1.17.12","v1.19.0-pre.4","1.19.0-pre.4","v1.18.5","1.18.5","v1.17.11","1.17.11","v1.19.0-pre.3","1.19.0-pre.3","v1.18.4","1.18.4","v1.17.10","1.17.10","v1.19.0-pre.2","1.19.0-pre.2","v1.18.3","1.18.3","v1.17.9","1.17.9","v1.19.0-pre.1","1.19.0-pre.1","v1.17.8","1.17.8","v1.18.2","1.18.2","v1.19.0-pre.0","1.19.0-pre.0","v1.18.1","1.18.1","v1.17.7","1.17.7","v1.18.0","1.18.0","v1.17.6","1.17.6","v1.18.0-rc.1","1.18.0-rc.1","v1.18.0-rc.0","1.18.0-rc.0","v1.17.5","1.17.5","v1.18.0-pre.3","1.18.0-pre.3","v1.17.4","1.17.4","v1.18.0-pre.2","1.18.0-pre.2","v1.17.3","1.17.3","v1.18.0-pre.1","1.18.0-pre.1","v1.17.2","1.17.2","v1.18.0-pre.0","1.18.0-pre.0","v1.17.1","1.17.1","v1.17.0","1.17.0","v1.17.0-rc.2","1.17.0-rc.2","v1.17.0-rc.1","1.17.0-rc.1","v1.17.0-rc.0","1.17.0-rc.0","v1.17.0-pre.3","1.17.0-pre.3","v1.17.0-pre.2","1.17.0-pre.2","v1.17.0-pre.1","1.17.0-pre.1","v1.17.0-pre.0","1.17.0-pre.0","v1.16.0-rc.0","1.16.0-rc.0","v1.16.0-pre.3","1.16.0-pre.3","v1.16.0-pre.2","1.16.0-pre.2","v1.16.0-pre.1","1.16.0-pre.1","v1.16.0-pre.0","1.16.0-pre.0","v1.15.0-pre.3","1.15.0-pre.3","v1.15.0-pre.2","1.15.0-pre.2","v1.15.0-pre.1","1.15.0-pre.1","v1.15.0-pre.0","1.15.0-pre.0","v1.14.0-snapshot.5","v1.14.0-rc.0","1.14.0-rc.0","v1.14.0-snapshot.4","1.14.0-snapshot.4","v1.14.0-snapshot.3","1.14.0-snapshot.3","v1.14.0-snapshot.2","v1.14.0-pre.2","1.14.0-snapshot.2","1.14.0-pre.2","v1.14.0-snapshot.1","1.14.0-snapshot.1","v1.14.0-snapshot.0","1.14.0-snapshot.0","v1.13.0-rc3","1.13.0-rc3","v1.13.0-rc2","1.13.0-rc2","v1.13.0-rc1","1.13.0-rc1","v1.13.0-rc0","1.13.0-rc0","v1.12.0-rc2","1.12.0-rc2","v1.12.0-rc1","1.12.0-rc1","v1.12.0-rc0","1.12.0-rc0","v1.11.0-rc2","1.11.0-rc2","v1.11.0-rc1","1.11.0-rc1","v1.11.0-rc0","1.11.0-rc0","v1.10.0-rc0","1.10.0-rc0","v1.9.0-rc1","1.9.0-rc1","v1.9.0-rc0","1.9.0-rc0","v1.8.0-rc1","1.8.0-rc1","v1.7.0-rc2","v1.7.0-rc1","v1.6.0-rc3","v1.6.0-rc2","v1.6.0-rc1","v1.5.0-rc2","1.5.0-rc2","v1.5.0-rc1","v1.3.0-rc1","v0.13.25","v0.13.22","v0.13.21","v1.0.0-rc9","v0.13.20","v0.13.19","v0.13.18","v0.13.17","v0.13.16","v0.13.15","v1.0.0-rc8","v0.13.14","v1.0.0-rc7","v1.0.0-rc6","v0.13.10","v0.13.8","v1.0.0-rc5","v0.13.6","v0.13.5","v1.0.0-rc4","v0.13.4","v0.13.2","v0.13.1","v1.0.0-rc1","v0.10.0","v0.9.0-rc1","v0.8.2","v0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49445.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:H"}]}
