{"id":"CVE-2026-32610","state":"PUBLISHED","title":"Glances's Default CORS Configuration Allows Cross-Origin Credential Theft","description":"Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, the Glances REST API web server ships with a default CORS configuration that sets `allow_origins=[\"*\"]` combined with `allow_credentials=True`. When both of these options are enabled together, Starlette's `CORSMiddleware` reflects the requesting `Origin` header value in the `Access-Control-Allow-Origin` response header instead of returning the literal `*` wildcard. This effectively grants any website the ability to make credentialed cross-origin API requests to the Glances server, enabling cross-site data theft of system monitoring information, configuration secrets, and command line arguments from any user who has an active browser session with a Glances instance. Version 4.5.2 fixes the issue.","publishedAt":"2026-03-18T16:31:12.154Z","updatedAt":"2026-03-18T16:59:40.327Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["nicolargo glances"],"affected":[{"vendor":"nicolargo","product":"glances","versions":[{"version":"< 4.5.2","status":"affected"}]}],"references":["https://github.com/nicolargo/glances/security/advisories/GHSA-9jfm-9rc6-2hfq","https://github.com/nicolargo/glances/commit/4465169b71d93991f1e49740fe02428291099832","https://github.com/nicolargo/glances/releases/tag/v4.5.2"],"weaknesses":["CWE-942"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32610.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32610","state":"PUBLISHED","datePublished":"2026-03-18T16:31:12.154Z","dateUpdated":"2026-03-18T16:59:40.327Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-12T14:54:24.270Z"},"containers":{"cna":{"title":"Glances's Default CORS Configuration Allows Cross-Origin Credential Theft","descriptions":[{"lang":"en","value":"Glances is an open-source system cross-platform monitoring tool.
