CVE-2026-29779 - UptimeFlare: Montior config / Credentials in `workerConfig` exposed in client-side JavaScript bundle

CVE ID :CVE-2026-29779
Published : March 7, 2026, 4:15 p.m. | 56 minutes ago
Description :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.
Severity: 7.5 | HIGH
