{"id":"CVE-2026-46611","summary":"Glances: XML-RPC Server Missing Host Header Validation Enables DNS Rebinding Attack","details":"Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, the Glances XML-RPC server (glances -s, implemented in glances/server.py) does not validate the HTTP Host header, leaving it vulnerable to DNS rebinding attacks. An attacker can exploit DNS rebinding to exfiltrate the full system monitoring dataset from a victim's browser. This vulnerability is fixed in 4.5.5.","aliases":["GHSA-w856-8p3r-p338"],"modified":"2026-06-26T18:29:21.720294493Z","published":"2026-06-25T18:00:47.735Z","related":["openSUSE-SU-2026:11122-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-346","CWE-350"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46611.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46611.json"},{"type":"WEB","url":"https://github.com/nicolargo/glances/releases/tag/v4.5.5"},{"type":"ADVISORY","url":"https://github.com/nicolargo/glances/security/advisories/GHSA-w856-8p3r-p338"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46611"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nicolargo/glances","events":[{"introduced":"0"},{"fixed":"988cad68474509557aa2db75f928393c00226979"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.5.5"}],"source":"AFFECTED_FIELD"}}],"versions":["v4.5.4","v4.5.3","v4.5.2","v4.5.1","v4.5.0.5","v4.5.0.4","v4.5.0.3","v4.5.0.2","v4.5.0.1","v4.5.0","v4.4.1","v4.4.0","v4.3.3","v4.3.2","v4.3.1","v4.3.0.8","v4.3.0.7","v4.3.0.6","v4.3.0.3","v4.3.0.2","v4.3.0.1","v4.3.0","v4.2.0","v3.4.0","v3.3.1","v3.3.0.1","v3.3.0","v3.2.7","v3.2.6","v3.2.5","v3.2.4.2","v3.2.4.1","v3.2.4","v3.2.3.1","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.7","v3.1.6.1","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0","v2.11","v2.10","v2.9.1","v2.9.0","v2.8.8","v2.8.7","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8","v2.7.1","v2.7","v2.7_RC1","v2.5.1","v2.5","v2.4.2","v2.4.1","v2.3","v2.2","v1.7.3","v1.7.2","v1.7.1","v1.7","v1.6.1","v1.6","v1.5.2","v1.5.1","v1.5","v1.4.2.1","v1.4.2","v1.4.1.1","v1.4.1","v1.4","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3","v1.2","v1.1.3","v1.1.2","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46611.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
