CVE-2025-57753Public exploitNetwork attack vector

Arbitrary file disclosure via traversal requests

Published Aug 21, 2025 · Updated Aug 21, 2025

Path traversal in vite-plugin-static-copy 0.4.3 through 2.3.1 and 3.0.0 through 3.1.1 allows remote attackers to read arbitrary files. The development-server middleware resolves an unnormalized request suffix against each configured src directory without verifying that the resulting path remains inside that directory. Exploitation requires an application to run an affected plugin version and explicitly expose its Vite development server to the network.
