Glances recently added DNS rebinding protection for the MCP endpoint, but prior to version 4.5.2, the main REST/WebUI FastAPI application still accepts arbitrary `Host` headers and does not apply `TrustedHostMiddleware` or an equivalent host allowlist. As a result, the REST API, WebUI, and token endpoint remain reachable through attacker-controlled domains in classic DNS rebinding scenarios. Once the victim browser has rebound the attacker domain to the Glances service, same-origin policy no longer protects the API because the browser considers the rebinding domain to be the origin. This is a distinct issue from the previously reported default CORS weakness. CORS is not required for exploitation here because DNS rebinding causes the victim browser to treat the malicious domain as same-origin with the rebinding target. Version 4.5.2 contains a patch for the issue.","published_at":"2026-03-18T17:47:25.929000Z","last_modified_at":null,"cvss_v3_score":5.9,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-346"],"nvd_references":["https://github.com/nicolargo/glances/security/advisories/GHSA-hhcg-r27j-fhv9","https://github.com/nicolargo/glances/commit/5850c564ee10804fdf884823b9c210eb954dd1f9","https://github.com/nicolargo/glances/releases/tag/v4.5.2"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:50.327474Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"nicolargo","vendor_name":"nicolargo","product_slug":"glances","product_name":"glances","version_start":"< 4.5.2","version_start_inclusive":true,"version_end":"< 4.5.2","version_end_inclusive":true,"cpe23_uri":"cve5:nicolargo:glances:< 4.5.2:< 4.5.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/nicolargo/glances/security/advisories/GHSA-hhcg-r27j-fhv9","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/nicolargo/glances/commit/5850c564ee10804fdf884823b9c210eb954dd1f9","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/nicolargo/glances/releases/tag/v4.5.2","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-03-18T17:47:25.929000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:09.779823Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:09.779823Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:09.779823Z","label":"CVSS score revised","source":"cvelistv5"}]}
