Cybersecurity researchers have disclosed details of a mass-scanning campaign that has targeted Vite deployments siphon sensitive data.<\/p>\n

The first is an automated effort aimed at internet-exposed Vite development servers that’s designed to steal cloud credentials, configurations from Amazon Web Services (AWS) and Microsoft Azure instances, and infrastructure state files, per F5 Labs<\/a>.<\/p>\n

The credential harvesting activity, observed in August 2026, has been found to leverage an exploit for CVE-2026-39364 (CVSS score: 8.2), a high-severity security flaw in Vite that could permit an unauthenticated attacker to bypass security restrictions via query parameter manipulation and leak sensitive data, including files specified by server.fs.deny.<\/p>\n

\u00abOn the Vite dev server, files that should be blocked by server.fs.deny (e.g., .env, *.crt) can be retrieved with HTTP 200 responses when query parameters such as ?raw, ?import&raw, or ?import&url&inline are appended,\u00bb Vite said in an advisory<\/a> for the flaw in April 2026.<\/p>\n
