{"id":"CVE-2026-29779","summary":"UptimeFlare: Montior config / Credentials in `workerConfig` exposed in client-side JavaScript bundle","details":"UptimeFlare is a serverless uptime monitoring & status page solution, powered by Cloudflare Workers. Prior to commit 377a596, configuration file uptime.config.ts exports both pageConfig (safe for client use) and workerConfig (server-only, contains sensitive data) from the same module. Due to pages/incidents.tsx importing and using workerConfig directly inside client-side component code, the entire workerConfig object was included in the client-side JavaScript bundle served to all visitors. This issue has been patched via commit 377a596.","aliases":["GHSA-36q9-v7p3-vj6v"],"modified":"2026-04-02T13:22:59.119043Z","published":"2026-03-07T15:19:38.593Z","database_specific":{"cwe_ids":["CWE-200"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29779.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29779.json"},{"type":"ADVISORY","url":"https://github.com/lyc8503/UptimeFlare/security/advisories/GHSA-36q9-v7p3-vj6v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29779"},{"type":"REPORT","url":"https://github.com/lyc8503/UptimeFlare/issues/198"},{"type":"FIX","url":"https://github.com/lyc8503/UptimeFlare/commit/377a5963c66ba9a798abebfe8d80378b053435e9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/lyc8503/uptimeflare","events":[{"introduced":"0"},{"fixed":"377a5963c66ba9a798abebfe8d80378b053435e9"}]}],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2026-03-04"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29779.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
