Vite 7.3.2

Automated Scans Exploit CVE-2026-39364 in Exposed Vite Dev Servers to Steal AWS and Azure Secrets

A large-scale automated campaign is actively scanning the internet for publicly exposed Vite development servers to exfiltrate sensitive files and cloud credentials. Attackers leverage CVE-2026-39364 to bypass server.fs.deny restrictions and read arbitrary files using crafted query parameters such as ?raw combined with ?import. The campaign has generated thousands of requests over several weeks, with telemetry from honeypots recording 807 sessions and roughly 32,000 events in a single month. Targets include .env files, terraform.tfstate, and other infrastructure-as-code artifacts that often contain AWS access keys and Microsoft Azure tokens. The vulnerable versions are Vite 7.1.0 through versions prior to 7.3.2 and Vite 8.x prior to 8.0.5. Part of the scanning traffic originates from Google Cloud IP ranges 34.x and 35.x. Organizations are urged to update immediately, restrict the dev server to localhost, and rotate any exposed cloud credentials.
