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."}], "lastModified": "2026-03-19T19:06:36.183", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nicolargo:glances:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3FC19E01-80F1-43BB-912C-39FE99143A59", "versionEndExcluding": "4.5.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
